A torn title page

In a Viennese archive rests a title page with a hole worn through it. The page heads an early copy of a symphony in E flat, and across its top, in a copyist’s hand, two words of dedication once stood, naming Napoleon Bonaparte, First Consul of France. Someone attacked those words with a blade or a pen point, scratching again and again until the ink, and then the paper itself, gave way. The attacker was the composer. The symphony became the Eroica, and that damaged page is the most eloquent object in the catalogue of Beethoven greatest works, because it announces, before a single note is heard, the division this article follows from the first work to the last: a catalogue built in large part by a man writing for the public of his own time, and closing with a body of work that appears to address almost nobody at all.

The page survives because the symphony circulated before it was published. Beethoven had the Eroica copied for private performance and for dispatch to publishers, and the copy preserved in Vienna carries the dedication in its Italian form, intitolata Bonaparte, with the second word worked over so violently that the surface of the sheet is abraded. Nothing else on the page is damaged. The music beneath the dedication was left untouched, which is part of what makes the object so instructive: the composer’s quarrel was never with the symphony. It was with the name he had placed above it, and with what that name had come to mean between the summer of composition and the winter of revision.

The claim this article defends is that the catalogue divides in two. One body of work is public in its bones: nine symphonies, the concertos, an opera, the occasional pieces, music designed to fill rooms, win patrons and argue its case before listeners who had paid to be persuaded. The other body is the late work, the final piano sonatas, the Diabelli Variations, the Missa Solemnis and the last quartets, written when deafness had closed the concert room to him and when the need to persuade any particular listener had weakened to the point of vanishing. The second body is where the music stops trying to convince an audience and starts following its own procedures wherever they lead. Ranking the works means holding both bodies in view at once, because the famous pieces mostly belong to the first and the most argued-over pieces mostly belong to the second.

Why would a composer deface his own title page? The question opens the catalogue because the catalogue is unintelligible without it, and this article will not answer it fully until the Eroica has been examined on its own terms in the sections ahead. The short answer involves a coronation in Paris and a pupil’s memoir written decades later. The long answer involves what Beethoven believed a symphony was for. The chronology of the man himself, his patrons, his hearing and his household, belongs to the companion account of Beethoven’s life and career, and is compressed here to the points where it touches the scores directly. What follows is about the works: what each one is, what it does that no other work in the catalogue does, how it was received, and where a listener new to all of it should begin.

Beethoven Greatest Works, the Opus Numbers and the Works Without Them

An opus number is a publisher’s device before it is anything else. When Beethoven issued his three piano trios as Opus 1 in 1795, the number told the Viennese trade that this set stood first in an authorised sequence of his publications, and every subsequent number extended that sequence until it closed with the String Quartet Opus 135, finished in the autumn of 1826. The sequence looks like a census of the output and behaves like nothing of the kind. A single number may hold one work or many. Opus 18 is six string quartets. Opus 2 is three piano sonatas. Opus 59 is three quartets and Opus 130 is one. Counting opus numbers therefore counts publication decisions, not compositions, and the distortion this creates in any total is the first fact a reader of the catalogue has to absorb.

How many symphonies did Beethoven write?

Nine, completed and numbered between the C major Symphony of 1800 and the D minor Ninth of 1824. Sketches for a tenth survive from his last years, extensive enough that Barry Cooper assembled a performing version of its first movement in 1988, but no tenth symphony entered the catalogue, and the count that performers, publishers and listeners use is nine.

The deeper distortion sits outside the sequence entirely. Across his career Beethoven wrote songs, dances, canons, variations, marches, folk song settings, incidental numbers and occasional pieces that he never published with an opus number, because no publisher wanted them in that form or because they were written for a single occasion and allowed to lapse. Georg Kinsky catalogued them in the twentieth century under the abbreviation WoO, Werke ohne Opuszahl, works without opus number, in a catalogue completed after Kinsky’s death by Hans Halm and published in 1955, and Willy Hess added a further catalogue of pieces Kinsky had missed. A substantial part of the catalogue carries no opus number, which distorts any count of the works: the numbered publications run to 138 entries once posthumous items are included, and the unnumbered remainder adds several hundred further pieces. Any sentence that begins with a total has already chosen what to leave out.

Behind both sequences stands a third catalogue, invisible in print: the sketchbooks, thousands of pages in which works were drafted, abandoned, cannibalised and reassembled across the whole career. The sketches complicate every total, because they contain completed pieces that were never copied out, movements that migrated between works, and at least one symphony, the Tenth, that exists nowhere else. A census of Beethoven is therefore a census of three different archives wearing one name, and the distortions compound one another.

The practical consequence for a works article is that fame and numbering pull in opposite directions. The pieces that anchor the public reputation sit inside the numbered sequence at its most visible points, the symphonies from Opus 55 onward, the concertos, the named sonatas. The pieces that complicate the reputation hide at the sequence’s edges or outside it altogether: a battle piece at Opus 91 that earned more than the symphonies, a set of variations on another man’s waltz that consumed four years, an overture to the only opera that waited a decade for its number, a fugue composed as a quartet finale and published under an opus number of its own after its parent work had already appeared without it. Scholars who present the catalogue in teaching materials, laying the numbered and unnumbered works side by side in chronological slides, can open such a presentation in a browser-based presentation viewer when the file needs to be shown rather than rebuilt. The catalogue resists tidy presentation in any format. It is a working life in print, with the gaps left in.

Public works and private works as two bodies

The division proposed in the opening section is not a division of quality, and it is only loosely a division of date. It is a division of address. The public works speak outward, to a room. They are built on rhetoric a first-time listener can follow: themes stated plainly and then argued over, contrasts sharpened until nobody can miss them, endings engineered to bring a hall to its feet. The Eroica, the Fifth, the Emperor Concerto and Fidelio are public works in this sense whatever their difficulties, because each one wants something from its audience and organises itself to get it. Even the Seventh Symphony, which has almost no programme and no text, behaves like an address to a crowd, a rhythm looking for bodies to move.

The late works speak in a different direction. The last three piano sonatas, the Diabelli Variations and the five final quartets were written for a performer alone at a keyboard or for four players in a room, in a city where the composer could no longer hear either. Their procedures are those of a mind testing material rather than presenting it: fugues that run far past the point of display, variations that exhaust a trivial theme until it turns profound, slow movements that suspend the normal contract between a theme and its development. The Missa Solemnis sits between the bodies and belongs fully to neither. It is a mass, the most public of forms, composed for the enthronement of an archbishop, and it is also the work Beethoven laboured over longest and described in his correspondence as his greatest, a score whose density defeated the institutions it was written for and whose first complete performance took place in another country.

Holding the two bodies apart matters because the arguments about Beethoven usually confuse them. The public works built the nineteenth century’s image of the composer as a heroic rhetorician, and that image then made the late works look like a falling away, a deaf man’s eccentricity, until performers and writers learned to hear them as a second summit rather than a decline. Lewis Lockwood, the biographer whose account of the music and the life sets the modern standard for the documentary record, treats the late period as a distinct creative phase with its own coherence rather than as an epilogue, and the works table below is organised on that principle. Each entry states whether the work addresses a room or a desk, and what it does that nothing else in the catalogue does.

The sections that follow take the bodies in the order the works appeared, because the division only becomes visible across the chronology. The early sonatas already contain the public manner in embryo. The middle symphonies build the reputation in public, one premiere at a time. The opera fails in public, twice, and is rebuilt. The occasional works include the greatest commercial success of the career, a fact the heroic image has never digested comfortably. Then the address turns inward, and the catalogue closes with works that were barely performed in their composer’s lifetime and are now treated as its summit. A ranking that ignores either body is a ranking of half a composer.

The early piano sonatas

The piano sonata was the form in which Beethoven first addressed the public in his own name, and he treated it from the outset as a laboratory with a shop window. The three sonatas of Opus 2, published in 1796 and dedicated to Haydn, already announce the scale of his ambitions: the first opens with a theme built for development rather than display, and the set as a whole asks to be judged against the best piano music in Vienna rather than against the teaching pieces that filled most publishers’ lists. Through the sonatas of the next decade, Opus 7, the three of Opus 10, the Pathétique and the pair of Opus 14, the pattern repeats. Each publication tests a procedure, lengthens a movement, darkens a slow movement or lets a finale run somewhere its predecessors had not gone.

The Pathétique, Opus 13, published in 1799, shows the laboratory at its most theatrical. Its slow introduction, marked Grave, is not a preface but a structural actor: it returns twice inside the first movement, interrupting the argument like a memory the music cannot put down, and its chords hang over the whole sonata. The nickname was the composer’s own or at least his publisher’s, printed on the title page, which distinguishes it from the more famous case two years later. The sonata Opus 27 No. 2 of 1801 carries no nickname from its author at all. The name Moonlight attached itself decades after his death, when the poet Ludwig Rellstab compared its opening movement to moonlight on Lake Lucerne, and the comparison proved so durable that it now conceals the work’s actual design, a sonata that withholds its fastest music until the finale and lets the celebrated slow movement function as a doorway rather than a destination.

The sonatas were also where the declared turning point of the career was first announced. The composer Carl Czerny, who had lessons from Beethoven as a boy and knew the early works from the inside, recalled him saying in 1802 that he was dissatisfied with what he had written so far and intended to take a new path. The sonatas of Opus 31, written that year, show the intention being acted on in private form before any symphony declared it in public: one of them opens with a slowly unrolled chord and breaks into recitative, as though an opera singer had wandered into a piano piece, and another builds its drama from a theme that seems to argue with its own accompaniment. The new path was a keyboard discovery before it was an orchestral one.

Two further features of the early sonatas matter for the catalogue as a whole. The first is numbering dishonesty of the innocent kind: the two easy sonatas of Opus 49 were composed years before their number suggests, in the middle 1790s, and published only in 1805, so a reader who trusts the sequence misdates them by a decade. The second is range. By the time of the three sonatas of Opus 31 in 1802, Beethoven had written sonatas that are comic, sonatas that are funerary, sonatas built on a single obsessive figure and sonatas that sprawl, and he had done it in the genre a young composer could publish without an orchestra, a patron’s stage or anyone’s permission. The symphonies that follow are inconceivable without that decade of keyboard experiments behind them, because the experiments taught him what a theme can be made to endure.

The first two symphonies and what they inherit

The First Symphony was premiered on 2 April 1800 at the Burgtheater, at a benefit concert Beethoven organised for himself, and it performs a deliberate double act. It presents its credentials in the inherited forms, a slow introduction, a sonata-form allegro, a dance movement, a finale with a Haydnish joke built into its opening, while quietly bending each of them. The bending starts with the first chord. A symphony in C major was expected to begin by confirming C major; this one begins with a chord that resolves away from the home key, so the work opens in a state of grammatical suspense that the introduction has to work to discharge. Contemporary reviewers heard the Haydn and Mozart lineage plainly and said so, and some heard the wind writing as excessive. The inheritance itself, the symphonic practice of Haydn and Mozart that a young composer in 1800 had to master before he could be allowed to break it, is surveyed in the history of classical composers, and the First Symphony is best read as a certificate of that mastery with the first alterations already pencilled in.

The Second Symphony, composed mostly in 1802 and premiered on 5 April 1803 at the Theater an der Wien on a programme that also introduced the Third Piano Concerto and the oratorio Christ on the Mount of Olives, stretches the certificate until it creaks. The slow introduction is longer and more searching, the first movement’s development ranges further, the minuet has become a scherzo with real violence in its accents, and the finale opens with a gesture so abrupt that one contemporary journal compared its effect to a wounded dragon thrashing rather than dying. Underneath the high spirits sits a structural confidence that the First Symphony only promised: movements are longer, codas have become second developments, and the whole work assumes a listener willing to follow an argument across three quarters of an hour.

The Second Symphony carries one further interest that the works record should not pass over. It was composed in the village of Heiligenstadt in the summer and autumn of 1802, the same months that produced a famous private testament in which the composer confronted his failing hearing and his despair over it. That document belongs to the biography, and the symphony is usually read against it, but the score itself gives almost nothing away: the most light-filled large work of his early career was written in the worst season of his life. The catalogue is full of such disconnections between circumstance and sound, and they are a standing warning against reading the works as a diary. The music says what it says. The documents say something else, and both records have to be kept.

Neither symphony is among the works that made the reputation permanent, and the catalogue is honest about that. What they contribute is the baseline against which the Eroica’s rupture can be measured, and one durable lesson in how Beethoven managed an inheritance. He did not discard the classical symphony. He kept its forms, its proportions and its rhetoric legible, and expanded the load each part was asked to carry, so that when the expansion finally burst the frame, the audience could still see the frame inside the ruin. The first two symphonies also established the pattern of his public career: self-organised concerts, programmes mixing the new symphony with a concerto and a vocal work, and reviews that praised the power while complaining about the length. The complaint about length would never entirely go away. It would become, in time, the point.

The Eroica and the change of scale

The Symphony No. 3 in E flat, Opus 55, was composed across 1803 and given its first public performance on 7 April 1805 at the Theater an der Wien, after private readings at the palace of Prince Lobkowitz, its eventual dedicatee, had tested it on informed ears. Its dimensions were the scandal and remain the fact from which everything else about the work follows. A symphony by Haydn or Mozart typically ran between twenty-five and thirty-five minutes. The Eroica runs close to fifty. The first movement alone, a vast sonata structure with its exposition repeated, occupies roughly a quarter of an hour, and it contains a development section of a size no symphony had carried, in the middle of which Beethoven introduces a theme that has not been heard before, as if the argument had generated new evidence halfway through. Near the development’s climax the harmony grinds through a chord of accumulated dissonance while the rhythm of the opening theme is hammered out of phase with itself, a passage early listeners found bewildering in the plainest sense and which the score justifies only by the scale of what surrounds it.

The second movement is a funeral march, a genre of public ceremony imported into the symphony at full length and in C minor darkness, with a major-key episode at its centre that sounds like memory breaking through mourning. The scherzo that follows is built on whispers and sudden eruptions, its trio given to three horns in a hunting call that fills the hall the march had emptied. The finale refuses the expected rondo and instead builds a set of variations on a theme Beethoven had already used twice, in a contredanse and in the finale of his ballet The Creatures of Prometheus, and which he would use again in a set of piano variations, as though the melody were a public possession he kept redeveloping. Barry Cooper, the scholar whose edition work and catalogue studies underpin much modern Beethoven scholarship, has shown how deeply the Eroica’s materials were worked in the sketchbooks before a note reached the orchestra, which corrects the old picture of the work as a single volcanic outpouring. It was planned like a campaign.

Two moments in the first movement became famous enough to stand for the whole problem of the work’s reception. Deep in the development, after the accumulated dissonance has reached its most grinding point, a quiet theme enters that has not been heard before, in a distant key, as if the symphony had to invent fresh material to escape the wreckage of its opening. And near the recapitulation the second horn steals in early with the opening theme over a chord that belongs somewhere else, a stroke so unexpected that Ries, standing near the composer at an early rehearsal, assumed the player had made a mistake and nearly earned himself a rebuke for saying so. Moments like these are why the work needed rehearsal time nobody was accustomed to granting a symphony, and why its first performers found it as exhausting to play as its first audiences found it to follow.

The immediate response was divided in a way that set the pattern for the next twenty years. The audience at the public premiere heard the Eroica on a programme where it competed with a symphony by Anton Eberl, and more than one report preferred Eberl’s work for its clarity. Reviewers in the Allgemeine musikalische Zeitung admired the power and deplored the proportions, one of them proposing in print that the symphony would gain by cuts, as though it were an overlong speech. Lobkowitz, who had paid for exclusivity in its first months, believed in it enough to fund those private performances, and Beethoven believed in it enough to hold the work back from publication until 1806 and then issue it with a title that turned its subject into an abstraction. What the work had changed, underneath the argument about its length, is the subject of the next section.

What the Eroica actually changed

The customary account says the Eroica revolutionised harmony, and the customary account is wrong in an instructive way. Its chords are not, bar by bar, much stranger than late Haydn. What the Eroica changed was duration and proportion: the sheer amount of time a symphonic argument could occupy, and the distribution of weight inside that time. The first movement alone is longer than some complete earlier symphonies, longer than the young Haydn’s entire early essays in the form, and its development section is not an episode between statements but the centre of gravity around which the statements orbit. Once a development could do that, the symphony’s contract with its listener had changed. The audience was no longer being shown a structure. It was being asked to remember one, across spans in which themes could be dismantled, lost and recovered transformed, and the demand itself became part of the meaning.

Why did Beethoven remove Napoleon’s name from the Eroica?

Because the hero changed. Beethoven had inscribed the symphony to Bonaparte as the champion of a republic; when news reached Vienna in 1804 that Napoleon had taken an imperial crown, the dedication became a lie about its subject. He struck the name out and eventually published the work to the memory of a great man instead.

That erasure is where the first open question of this article can now be closed. The story in its familiar form comes from Ferdinand Ries, Beethoven’s pupil, who recalled in memoirs published in 1838 that he had brought the composer the news of the coronation and watched him rage at the betrayal and tear the title page in two. The memoirs were written decades after the event and deserve the caution due to any such source, but the physical evidence does not depend on them. The copyist’s score in Vienna shows the dedication attacked on the page itself, the name scratched out with a force that wore through the paper, exactly as the cold open of this article described. Whatever precisely happened in the room, the document records an act of deletion, and the publication of 1806 records its outcome. The symphony appeared dedicated to Lobkowitz, who had paid for it, and titled in Italian as a heroic symphony composed to celebrate the memory of a great man. The living hero had been replaced by an idea of heroism, which the music, with its funeral march for a protagonist who never appears, had arguably been about from the start.

The change is legible inside Beethoven’s own output, which is the cleanest evidence for it. No symphony he wrote after the Eroica retreats to the scale of the first two. The Fourth, often described as slender, is slender by choice and proportion rather than by modesty of means, and it knows the Eroica stands behind it. The Fifth compresses the new scale into violent concentration. The Sixth expands it across five movements. The Seventh and Eighth test whether rhythm and wit can fill the enlarged frame. The Ninth finally exceeds the Eroica outright, in length, in forces and in ambition, and it does so by adding the one element the Eroica had simulated with instruments alone: voices. A catalogue in which a single work resets the minimum size of every successor is a catalogue with a hinge in it, and the hinge is at Opus 55.

The other changes the Eroica made follow from the change of scale. A symphony could now carry a narrative shape without a text, birth of a theme, struggle, death, commemoration and renewal distributed across four movements; it could import the public genres, the march and the ceremonial hymn, and subject them to private argument; and it could make demands on professional orchestras that redefined what an orchestra was for. How those demands operate at the level of phrase, key and orchestral spacing is the business of the companion study of Beethoven’s musical style, and is deliberately compressed here. What belongs to a works article is the consequence. After 1805, every ambitious symphony written in Europe was composed in the Eroica’s shadow or in declared reaction against it, and Beethoven himself spent the rest of the catalogue exploring the space the work had opened, beginning, characteristically, by doing something entirely different twice in a single evening.

The Fifth Symphony

The Symphony No. 5 in C minor, Opus 67, was sketched as early as 1804, completed across 1807 and 1808, and premiered on 22 December 1808 at the Theater an der Wien in the most famous bad concert of the century. The Akademie that evening ran for some four hours in an unheated hall and contained the first performances of both the Fifth and Sixth symphonies, the Fourth Piano Concerto, movements from the Mass in C and a Choral Fantasy composed at speed to close the programme, all played by an orchestra that had been granted almost no rehearsal. The printed programme even listed the two symphonies in reverse order, calling the Pastoral fifth and the C minor sixth, a confusion corrected when the works were published. That the Fifth survived its birth conditions to become the most recognisable symphony ever written is the central reception paradox of the catalogue.

The work itself is built from a cell of four notes, three short and equal, struck on a single pitch, and a fourth that falls and holds, a rhythm more than a melody. Beethoven subjects that rhythm to an entire symphony. It saturates the first movement, in which almost every bar is accountable to it. It returns pianissimo in the scherzo, transformed into a spectral tread. It underlies the finale’s blaze by contrast, and the finale itself contains the boldest structural stroke in the work: before its recapitulation, the scherzo’s ghost steals back, pizzicato and held breath, so that the triumph has to be won a second time. The finale also enlarges the orchestra at a stroke, bringing in trombones, piccolo and contrabassoon for the first time in a symphony, instruments held in reserve until the moment of emergence from the scherzo’s darkness. The whole design, from a four-note cell to an expanded orchestra, is a single argument about growth under pressure.

Its interpretation acquired, early on, a label the composer never published. Anton Schindler, who served as Beethoven’s unpaid secretary in the final years and became his first biographer, claimed in his reminiscences that the composer had described the opening as fate knocking at the door. Schindler is a figure this article treats as a subject rather than a source: his biography preserved genuine material and also reshaped the record, inserting entries into the conversation books and polishing anecdotes until they gleamed, and modern documentary scholarship, including Barry Cooper’s work on the surviving papers, handles his testimony with open caution. The fate story belongs to Schindler’s Beethoven, not necessarily to Beethoven’s. What the record shows without him is a work whose first audiences were startled rather than converted, and whose standing was made by print: the composer and critic E. T. A. Hoffmann, reviewing the Fifth in the Allgemeine musikalische Zeitung in 1810, placed it among the most significant works of the age and heard in it an ordered vastness rather than noise. Hoffmann’s review, not the premiere, is the moment the Fifth began its journey from difficult new symphony to universal property.

One detail inside the score explains why performers keep returning to it. In the recapitulation of the first movement, at the point where the argument should simply resume its course, the oboe breaks ranks and inserts a short cadenza, a grieving human voice inside the machine, before the cell closes over it again. The gesture lasts seconds and has been remarked on for two centuries, because it shows the design thinking against itself: the most disciplined movement Beethoven ever wrote contains a moment of pure, unmotivated pathos, placed exactly where discipline should be absolute. The sketchbooks show the movement’s material being hammered into shape across four years, alongside the very different world of the Pastoral, which occupied the same desk in the same seasons. Concentration of this order was manufactured, not bestowed, and the Fifth is the catalogue’s clearest evidence that its effects were engineered by revision.

The Sixth and the problem of description in music

The Symphony No. 6 in F major, Opus 68, the Pastoral, shares its premiere with the Fifth and contradicts it in almost every particular. Where the Fifth is an argument, the Sixth is a sequence of states. It has five movements rather than four, and Beethoven gave each a descriptive heading: arrival in the country, a scene by a brook, a peasants’ dance, a storm, and a shepherds’ hymn of thanksgiving after the weather has passed. The headings made the work the test case for a question the catalogue keeps asking, which is how far instrumental music can describe the world before it stops being music and starts being illustration. Beethoven’s own position was printed with the work and has been quoted ever since in paraphrase: the symphony was to be understood as the expression of feeling rather than painting, a recollection of country life as the feelings it arouses, not a set of sound effects.

The score honours the distinction more carefully than its reputation suggests. The brook movement does contain bird calls near its close, a nightingale in the flute, a quail in the oboe and a cuckoo in the clarinets, each identified in the score, but they arrive as an ornament on a long, slow harmonic meditation that has been flowing like water for ten minutes without depicting anything at all. The storm is genuinely violent, with the orchestra’s full weight and the piccolo shrieking at its top, yet it functions structurally as the interruption a pastoral world requires, the event that gives the finale’s gratitude its occasion. Even the peasants’ dance builds its comedy from craft, a village band’s rhythms and a tune that keeps nearly falling over its own feet, rather than from any literal scene. Description in the Pastoral is real but rationed, and the rationing is the aesthetic position.

Reception has always been kinder to the Sixth than to any other Beethoven symphony, because it asks the least specialised knowledge of its listener and because its programme gives the memory something to hold. The catalogue needs it for a structural reason too. Written concurrently with the Fifth, premiered on the same night, it proves that the Eroica’s expansion of scale was a choice rather than a compulsion. The same composer, in the same years, could build a symphony from a four-note cell and a symphony from a walk in the woods, and the contrast between them is the strongest evidence that the public works were designed as addresses to an audience, each calculating its effect by different means. The Pastoral calculates charm. It has never stopped working.

The debate it started has never stopped either. When Eduard Hanslick published his treatise on musical beauty in 1854, arguing that music’s content is sound in motion and nothing beyond it, the descriptive symphony was the position he was arguing against, and the Pastoral, with its titled movements and identifiable birds, was the exhibit every party to the quarrel reached for. The depiction camp heard the brook and the storm as proof that music could carry the world into the concert room. Hanslick’s party heard the same passages as decoration on structures that would stand without them. Beethoven’s printed qualification sits exactly on the fault line between the two, which is why the Sixth remains the most argued-over gentle work in the repertory. Its second movement makes the case for the defence better than any treatise: nearly a quarter of an hour of music that flows in a single unhurried metre, its harmony drifting so slowly that time itself seems to be the subject, and its effect depends on nothing a listener must be told. The description was the door. The room beyond it is pure duration.

The Seventh and rhythm as subject

The Symphony No. 7 in A major, Opus 92, composed across 1811 and 1812, received its premiere on 8 December 1813 in the hall of the University of Vienna, at a charity concert for soldiers wounded in the recent fighting at Hanau. The programme was shared with Wellington’s Victory, and the orchestra that night was a roll call of Viennese musical life, with the violinist and composer Louis Spohr among the players. Spohr left an account of the rehearsals in his autobiography, describing Beethoven conducting with his whole body, crouching under quiet passages and leaping at loud ones, and the concert succeeded so completely that it was repeated four days later. The second movement, the Allegretto, had to be played again at the premiere itself, an honour the more striking because the movement is not a tune but a procession, built on a single rhythm that walks from the first bar to the last while the harmony grieves above it.

Rhythm is the Seventh’s subject in a sense no earlier symphony attempts. The first movement, after the longest and most monumental slow introduction Beethoven had yet written, releases into a dance metre so pervasive that the themes themselves seem to be generated by the beat. The scherzo gallops and then halts for a trio whose solemn, drone-based chorale exists mainly to make the gallop funnier on its return. The finale is the most rhythmically obsessive music he had written to that date, a whirling movement in which accents land like blows and the coda drives the orchestra to a volume and speed that Spohr, for one, found pushed past taste into deliberate extravagance. Wagner, writing his Beethoven essay in 1870, called the Seventh the apotheosis of the dance, and the phrase has stuck because the work supports it: strip the notes of their pitches and the rhythms alone would still identify every movement.

In the catalogue’s argument the Seventh marks the point where the public manner reaches its highest efficiency. It is a symphony with no programme, no text, no dedication to a hero and no narrative crutch, which nonetheless held a wartime audience completely and has never left the repertory since. It also complicates the two-bodies thesis in a productive way. The Seventh is public music of absolute purity, addressed to a room and content to be nothing else, and it was composed in the same decade in which the first signs of the inward turn can be heard elsewhere in the output. The bodies do not succeed each other like dynasties. They coexist, and the composer chose between them work by work.

The Seventh also played a part in the strangest chapter of the public career, the season of the Congress of Vienna. When the rulers of Europe assembled in the capital in the autumn of 1814 to redraw the map after Napoleon, Beethoven was the city’s presiding musical celebrity, and the Seventh, along with the battle piece, was performed at the grand concerts of the season before audiences of crowned heads. The symphony dedicated to Count Moritz von Fries thus became, for a few months, something close to a state soundtrack, the sound of a capital congratulating itself. Its delayed publication, the full score did not appear until 1816, shows the economics behind the glory: the work earned its composer fame faster than money, and the fame was of the kind that filled halls while publishers haggled. No other symphony in the catalogue had so public a life so quickly, and the contrast with the quartets of the following decade, written for no occasion and barely performed, measures the distance the career travelled between the Congress and the silence that followed it.

The Eighth and the question of lightness

The Symphony No. 8 in F major, Opus 93, was composed in 1812 and premiered on 27 February 1814, on a programme where the audience, still in love with the Seventh, received it with relative coolness. It is the shortest of the later symphonies and the most deliberately deceptive. There is no slow introduction and no true slow movement. In the slow movement’s place stands an Allegretto scherzando whose ticking accompaniment behaves like a mechanism, a joke about measured time delivered deadpan for four minutes. The third movement revives the old-fashioned minuet that Beethoven had supposedly abolished, written with a courtly stiffness that reads as parody and affection at once. The finale is the longest and most learned movement of the four, a sonata structure of real weight disguised as a romp, and it contains the work’s most quoted practical joke, a blaring note from a foreign key that crashes into the argument and is then, with enormous comic patience, explained by the harmony until it becomes the most logical note in the movement.

The Eighth’s reputation suffered for a century from being measured against its neighbours, as though brevity were a confession of reduced ambition. Czerny recalled Beethoven himself making the contrary case with some heat: the Eighth, the composer insisted, was not less successful than the Seventh because it was worse, but because it was better, a judgment delivered with a performer’s vanity and a craftsman’s accuracy in roughly equal measure. The work’s lightness is engineered, not found. Its transitions are sleights of hand, its jokes are load-bearing, and its final movement’s coda expands to a scale that quietly refutes the idea that the whole symphony is a trifle. In the two-bodies account the Eighth is a public work playing at being a private amusement, the composer demonstrating that after the Eroica and the Seventh he could still choose smallness, and make the choosing itself feel like a form of wit. It is the symphony musicians tend to love out of proportion to its fame, which is a different kind of ranking from the public one, and the works record should register both.

Even the ticking movement has a documented private source, which sharpens the joke. In 1812 Beethoven composed a farewell canon for Johann Nepomuk Maelzel, the inventor and showman then promoting the metronome, building the little piece on a syllabic tick that imitated the device. The rhythm of that canon is the rhythm that ticks away inside the Eighth’s Allegretto scherzando, enlarged into a movement. A mechanical timekeeper the composer had mocked affectionately in a party piece became the heartbeat of a symphony movement, which tells the reader something important about how this catalogue works: material was never wasted, occasions were never merely occasions, and a joke written for a dinner could be reborn, years of craft later, as the most quietly original movement in a symphony that its first audience thought too slight to take seriously. The Eighth repays the attention its premiere withheld.

The piano concertos

Beethoven’s relationship with the piano concerto was the relationship of a performer with his own showcase, and the five numbered concertos trace his performing life from arrival in Vienna to withdrawal from the platform. The numbering, once again, lies politely about the order. The concerto published as No. 2, in B flat, Opus 19, was largely composed first, in the 1790s, and revised for years; the concerto published as No. 1, in C major, Opus 15, came later and struck him as the grander statement. Behind both stands an E flat concerto written in Bonn at fourteen, in 1784, of which only the piano part survives, catalogued among the unnumbered works and reconstructed by later editors. The numbered sequence thus contains five concertos and conceals a sixth, a pattern by now familiar: the catalogue’s official face is tidier than the workroom.

The Third Concerto, in C minor, Opus 37, premiered on 5 April 1803 with the composer as soloist, supplies the period’s most telling image of that workroom. Ignaz von Seyfried, who turned pages for him, recorded afterward that the piano part he was supposed to follow consisted largely of blank leaves and a few scrawled cues, because Beethoven had not found time to write the solo out and was playing it from memory and invention while conducting his own premiere from the keyboard. The Fourth Concerto, in G major, Opus 58, breaks the concerto’s oldest rule in its first bar: where convention demanded an orchestral exposition before the soloist dared speak, this work opens with the piano alone, playing a quiet phrase that the orchestra then repeats as though considering it. Its slow movement stages a dialogue so extreme that Liszt later read it as Orpheus pleading with the Furies, the orchestra’s fierce unison interjections softening under the piano’s persistence until they yield, an interpretation that has clung to the work ever since. The Triple Concerto, Opus 56, for piano, violin and cello, written in 1804 with the piano part shaped for his pupil Archduke Rudolph, completes the group: an experiment in distributing the solo role among three players that his contemporaries barely heard and posterity has never quite known whether to love.

The concertos preserve one more class of evidence that belongs to the works record: the cadenzas. In 1809 Beethoven wrote out cadenzas for the first four piano concertos, a task he undertook for the use of Archduke Rudolph, and the documents show him fixing in notation what he had previously improvised in the hall, converting the soloist’s licensed moment of freedom into composed text. The Third Concerto’s debt is also documented in its very key and bearing: Mozart’s C minor concerto, a work Beethoven knew intimately and had performed, stands behind it as model and provocation, and the younger composer’s homage consists of taking the model’s darkness and doubling its scale. A concerto cycle that begins in declared apprenticeship and ends with the soloist opening the work alone, unintroduced, has travelled the whole distance of the early career, and it travelled it in public, one premiere at a time.

What the five concertos collectively document is a transfer of power. In the early works the soloist is a brilliant guest inside an orchestral argument. By the Fourth, the piano initiates, persuades and overrules, and the orchestra has become the body it must convince. The concerto had been Mozart’s most social form. Beethoven made it a drama of one against many, and then, in the work that closes the line, he made the one so commanding that the drama threatened to end.

The Emperor and the end of the concerto line

The Piano Concerto No. 5 in E flat, Opus 73, was composed in 1809, the year Napoleon bombarded Vienna and Beethoven took shelter, by his own later account to friends, in a cellar with pillows pressed over his damaged ears. He did not premiere it and could not have: his career as a concerto soloist had effectively closed with the Fourth in 1808. The work was introduced in Leipzig on 28 November 1811 by Friedrich Schneider, and Vienna heard it in February 1812 with Czerny as soloist. The nickname Emperor was attached not by the composer but by the London publisher Johann Baptist Cramer, and it has misled listeners ever since into hearing a monument where the score offers something more interesting, a concerto about ceremony and what ceremony costs.

The opening is the boldest in any concerto of the period. The orchestra strikes a single chord and the piano erupts over it in a full written-out cadenza, not at the end of the movement where display was licensed, but in its first seconds, and the exchange repeats until the exposition proper begins with the hierarchy settled: the soloist is not a guest in this house but its co-author. The slow movement is a hymn of extreme simplicity, muted strings carrying a melody the piano then dreams over, and its final notes dissolve directly into the rondo’s theme, whispered before it is danced, one of the great transitions in the catalogue. The finale itself is a rondo of public splendour, the public body at full stretch.

The Emperor’s key deserves a word of its own in the record. E flat major was Beethoven’s ceremonial key, the key of the Eroica, of the early concerto he had written at fourteen, and of the piano trio that opens the numbered works, and the choice announced the concerto’s public character before the soloist had played a note. What the soloist then plays sustains the announcement in an unexpected register: for all its scale, the Emperor contains some of the most inward music in any concerto of the time, above all the slow movement, in which the piano decorates the orchestra’s hymn with figuration of a delicacy that belongs to the private body of work, years before that body had announced itself. The two bodies of the catalogue are present inside this single concerto, the parade ground and the study sharing one binding. That doubleness, as much as the nickname he never chose, is the work’s identity.

Then the line stops. Beethoven sketched the opening movement of a sixth piano concerto in D major in 1815 and abandoned it, and the sketch, catalogued by Hess and studied by Nicholas Cook among others, stands in the workroom as evidence that the form itself had been exhausted rather than the composer. He had nothing left to prove against an orchestra. The concerto had been the instrument of his arrival in Vienna, the vehicle of his fame as a performer, and the genre in which his deafness bit earliest and hardest. Its abandonment after the Emperor is the first clear structural sign in the catalogue that the public career was ending, years before the late works made the fact impossible to ignore.

The violin concerto and its failed premiere

The Violin Concerto in D major, Opus 61, was written in 1806 for Franz Clement, the leader of the orchestra at the Theater an der Wien and one of the most complete violinists of the age, a musician famous for sight-reading anything placed before him. The concerto’s premiere, at Clement’s benefit concert on 23 December 1806, tested that fame in a way Clement can hardly have welcomed. By contemporary report the solo part was finished so late that he played substantial stretches of it at sight, and the evening’s structure did the new work no favours either: between its first movement and the remainder, the soloist entertained the house with a display piece of his own, performed on a single string with the violin held upside down. The concerto’s long, serene argument, in which the soloist more often floats above the orchestra than contests with it, stood little chance amid the cabaret, and the reviews were cool.

The work then did something that inverts the normal story of the catalogue. Beethoven, needing the piece to earn, transcribed it himself as a piano concerto at the request of the London publisher Muzio Clementi, and for that version, published as Opus 61a, he wrote cadenzas, including a first-movement cadenza in which the piano argues with the timpani, an extraordinary conception that pianists have prized ever since and violinists have envied from outside. The violin original, meanwhile, slept. It was revived in London in May 1844, when Joseph Joachim, not yet thirteen years old, performed it with Mendelssohn conducting the Philharmonic Society, and the revival amounted to a second premiere: the concerto the Viennese of 1806 had shrugged at was heard, thirty-eight years on, as one of the summits of the instrument’s literature. The most radical fact in this article’s ladder of revelations is simply that the violin concerto failed at its premiere and waited decades for a performance that established it, and the lesson generalises across the late catalogue. Beethoven’s works repeatedly required a later generation of performers to become themselves.

The failure also had a commercial afterlife worth recording, because it shows how the catalogue earned its keep in a market with no royalties for performance. Publication was the payday, and a failed premiere depressed a work’s price. Beethoven nonetheless placed the concerto with the Viennese publisher of the Bureau des Arts et d’Industrie in 1808, with a dedication to his friend Franz Brentano, and the piano transcription for Clementi doubled the asset for the English market. The piece that had failed as an event was carefully managed as property. When Joachim and Mendelssohn restored it to the stage in 1844, they were recovering a work its composer had never stopped treating as valuable, whatever the benefit concert of 1806 had suggested. The works record and the property record tell different stories about the same score, and both are true.

The concerto’s design explains both the failure and the establishment. Its first movement opens with five quiet beats on the timpani, a rhythm the whole movement will spend itself exploring, and then unfolds at a breadth no concerto had attempted, the soloist entering not with the theme but with a meditation high above it. The slow movement is a set of variations so hushed that the orchestra sometimes seems afraid to breathe, and the finale, a hunting rondo of deceptive lightness, releases the accumulated stillness into dance. In 1806, length and serenity read as emptiness. Heard by Joachim’s generation, they read as the essence of the work: a concerto that replaced combat with contemplation, written by a composer who had already written combat better than anyone alive.

The Razumovsky quartets

The three string quartets of Opus 59, composed in 1806, were commissioned by Count Andrey Razumovsky, the Russian ambassador to Vienna, whose palace maintained a resident quartet led by Ignaz Schuppanzigh that would give many of the chamber works their first hearings. The commission explains the quartets’ most famous feature. The first two each contain a Russian theme, drawn from a published collection of folk songs, worked into their fabric as a compliment to the patron: in the first quartet the theme arrives in the finale and is treated with a contrapuntal seriousness entirely out of proportion to its simplicity, while in the second it is set in the trio of the scherzo, harmonised with deliberate splendour. The compliment, in Beethoven’s hands, becomes an investigation of what a folk tune can bear.

Scale is the quartets’ larger provocation. A string quartet in 1806 was still understood as conversation among four equals, sized for a room. The Razumovsky quartets are sized for a hall and structured like symphonies, with slow introductions, vast first movements and slow movements of an inwardness the genre had not housed. The slow movement of the first quartet, one of the longest he had written, unfolds like an aria for the cello over a held breath; the second quartet drives its argument through a first movement of concentrated fury and a finale of folk-dance energy; the third, without a Russian theme, closes with a fugue that seems to test the players’ technique as a form of sport. The early response was open bewilderment. A Leipzig review granted the works depth and finish and judged them not generally comprehensible, and the cellist Felix Radicati is reported to have told the composer to his face that they were not music, receiving the answer that they were not for him but for a later age. The exchange survives through the early biographical tradition rather than through any document, and should be weighted accordingly, but the fact it was asked to carry, the quartets’ difficulty as a first impression, is confirmed by every contemporary review that survives.

The later age arrived on schedule. The Razumovsky set became the foundation of the quartet as a major form, the point at which the genre’s centre of gravity shifted from sociability to statement, and every serious quartet written after them has had to decide where it stands in their territory. For the catalogue’s chronology they also mark a hinge in the chamber music: behind them stands the pleasant mastery of Opus 18, ahead of them the harp and serioso quartets and then, after a long silence in the genre, the final five.

The third quartet deserves its separate sentence in the record, because it points furthest forward. Without a Russian theme to carry its compliment, it relies on wit and velocity, and it ends with a fugal finale of a brilliance that earlier quartet writing would have considered a category error, counterpoint displayed as athletic event. Beethoven would return to the quartet fugue at the end of his life in circumstances of far greater extremity, and the line from this finale to the Grosse Fuge is one of the catalogue’s clearest through routes. Published in 1808 and dedicated to Razumovsky like its companions, the set circulated in print while its composer moved on to the symphonies of 1808, and the quartets waited, as the violin concerto had waited, for performers equal to their demands to make them repertory. Schuppanzigh’s players had been equal from the start. The audience was the part that had to be educated, and the education took a generation. The quartet would become, in the end, the vessel of the most private music he ever wrote, and the Razumovskys are where that vessel was first built to full size.

The Waldstein and Appassionata sonatas

The two great piano sonatas of the middle years make a matched pair of opposites. The Waldstein, Opus 53 in C major, composed across 1803 and 1804, is dedicated to Count Ferdinand von Waldstein, the Bonn patron whose album entry of 1792, the catalogue’s most famous piece of prophecy, told the departing young composer that with diligence he would receive Mozart’s spirit from Haydn’s hands. The sonata opens with a pulse rather than a theme, repeated chords throbbing in a low register while the harmony slides underneath them, and its original slow movement caused the work’s one famous crisis: Ries recalled that a friend of the composer’s judged the sonata too long, and Beethoven, furious and then reflective, removed the movement entirely. The Andante favori, as the discarded movement became known when it was published separately, was replaced by a brief, shadowy introduction that leads directly into the finale, a rondo whose theme emerges out of pedal-blurred shimmering and whose closing pages demand octave glissandos and sustained trills that stretched the piano writing of the day to its limit.

The Appassionata, Opus 57 in F minor, composed across 1804 and 1805 and dedicated to Count Franz von Brunsvik, is the Waldstein’s dark twin. It opens with a whisper, the same arpeggiated figure stated twice in the depths and then swollen without warning, and it governs its first movement by a rhythmic cell that knocks through the structure at every level. Its slow movement, a theme with variations of extreme stillness, is not granted a conclusion: the last variation is interrupted by a diminished chord struck twice, and the finale, a perpetual motion of unusual ferocity, pours out of the interruption without a pause. That finale never relents, and its coda accelerates into a final presto that feels less like an ending than an exhaustion of the material’s capacity to resist. The nickname, like the Moonlight’s, is not the composer’s: a Hamburg publisher attached Appassionata to a four-hand arrangement issued in 1838, eleven years after Beethoven’s death, and the trade name simply outlasted the work’s anonymity.

Between them the two sonatas state the middle period’s keyboard aesthetic as completely as the Eroica states its orchestral one. The Waldstein is radiance engineered, the Appassionata is pressure contained until containment fails, and both are public works in the precise sense this article has been using: they address an imagined listener across a room, they make their effects with maximum clarity, and they were published, performed and argued over in their composer’s lifetime. The piano sonata had begun as Beethoven’s shop window. In these two works the shop window becomes a stage, and the distance from here to the solitary landscapes of the last sonatas, written when the stage had gone dark, is the distance the catalogue still has to travel.

Posterity ratified the pair quickly. The Appassionata in particular was singled out within years of publication as the summit of his piano writing to that date, and it remained for decades the sonata by which virtuosos were measured, a performing test as much as a composition. The Waldstein traveled almost as fast, its finale’s shimmering pedal effects posing questions about the instrument itself that piano builders spent the century answering. Both works were dedicated within the composer’s working circle of patrons and friends, both were published while their effects were still news, and both belong entirely to the economy of the public career, fame converted into print and print into income. After them the sonata output thins dramatically: a handful of smaller sonatas across the next decade, then silence, then the Hammerklavier detonating the genre from inside. The shape of that curve, plenitude, pause, explosion, is the piano music’s version of the catalogue’s whole story.

Fidelio and three versions of one opera

Beethoven wrote one opera, and he wrote it three times. The subject had been chosen with care. Jean-Nicolas Bouilly’s libretto about a wife who disguises herself as a man to penetrate a political prison and rescue her husband had already been set in French and in Italian before Joseph Sonnleithner adapted it into German, and its theme, conjugal fidelity defeating tyranny in the decade of the Bastille, matched Beethoven’s deepest political instincts. The story in its final form runs as follows. Leonore, disguised as a youth named Fidelio, takes service with Rocco, jailer of a fortress where the governor, Don Pizarro, holds her husband Florestan in a secret cell below the prison yard, starved and awaiting murder to silence what he knows. The jailer’s daughter falls in love with the disguised Fidelio, to the horror of her official suitor. Leonore earns Rocco’s trust, persuades him to let the prisoners briefly into the daylight, and finally descends with him to dig a grave in the cell itself, recognises the wasted prisoner, and holds Pizarro at pistol point until a trumpet from the tower announces the arriving minister whose inspection ends the tyranny.

The plot was common property before it was his. Gaveaux had set Bouilly’s text in Paris in 1798, Ferdinando Paer’s version reached Dresden in 1804, and Simon Mayr’s followed in Italy in 1805, so Beethoven was entering a competition as much as a genre, claiming the story for German opera against its French and Italian owners. The Leonore of the first production was Anna Milder, a singer of formidable dramatic power for whom the title role was tailored and whose instrument shaped its writing at every stage; she would return to the part in triumph in 1814, and the role’s demands, pages of sustained declamation over a full orchestra, remained calibrated to her for as long as the opera was his to revise.

The music for this plot contains pages that stand with anything in the catalogue. The prisoners’ chorus, in which the inmates emerge blinking into the light and sing in hushed wonder before being driven back, compresses the opera’s whole politics into one scene. The quartet in the first act, four characters singing the same serene melody in canon while meaning four incompatible things by it, is a miracle of construction. The trumpet signal, sounding from offstage at the moment of maximum danger, is the most famous single orchestral effect he ever devised, a sound that is simultaneously a plot event and a judgment on the plot. Florestan’s aria, opening the second act from darkness and delirium, begins with an orchestral cry and moves through a vision of his wife as an angel, and the grave-digging duet that precedes it gives Leonore and Rocco shovels for accompaniment and silence for scenery.

Yet the opera exists in three complete versions, Leonore in 1805, a revised Leonore in 1806, and Fidelio in 1814, and the question of why one opera needed three complete versions is the second open question of this article. The first version, three acts long, opened at the Theater an der Wien on 20 November 1805, one week after Napoleon’s army had occupied Vienna and scattered the opera’s natural audience, and it failed in three performances before a house thin enough to count. The 1806 revision, cut to two acts, managed two performances before a quarrel ended the run. Only the third version, nine years after the first, succeeded, and it has held the stage since. A composer who solved every other genre he touched at the first or second attempt spent a decade solving this one, and the record of the solving is preserved in unusual completeness because he never threw the failures away.

Why Fidelio was rewritten twice

Why does Fidelio exist in three versions?

Because the opera failed twice for different reasons and he refused to abandon it. The 1805 version was long, loosely built and staged in an occupied city; the 1806 revision tightened it and died in a quarrel over money; the 1814 version, with its libretto reshaped and its music recomposed, finally worked.

The 1805 failure was overdetermined. The occupation emptied the theatre, but the score itself was vulnerable: the opera opened with a long stretch of domestic intrigue in the jailer’s household, charming music that delayed the rescue plot until the audience’s patience had been spent, and its three acts carried scenes Beethoven the symphonist could not resist expanding past their dramatic function. The revision of 1806, prepared with his friend Stephan von Breuning, cut the work to two acts, merged and tightened numbers, and played twice in March and April before Beethoven, convinced the management was cheating him of receipts, quarrelled with the theatre’s director and withdrew the piece in anger. The evidence of that quarrel survives in his own correspondence, furious and specific, and it cost the opera eight years.

The 1814 rescue was a collaboration conducted in a changed Vienna. Georg Friedrich Treitschke, poet and stage manager, rebuilt the libretto with a professional’s ruthlessness: dialogue was cut, the order of numbers adjusted, Florestan’s aria enlarged into the opera’s dark centrepiece, and the final scene opened outward into a public celebration. Beethoven recomposed on a scale that amounted to a new opera wearing an old one’s plot, and he replaced the overture yet again, discarding the symphonic Leonore overtures for a compact curtain-raiser that did its work in the theatre rather than the concert hall. The four overtures are the revision history in miniature. The second and third Leonore overtures, from 1805 and 1806, are symphonic poems too large for the pit, and the third became so beloved in the concert hall that conductors later inserted it into the opera itself, a tradition Mahler entrenched. The overture now called Leonore No. 1, written in 1807 for a Prague production that fell through, was published after his death as Opus 138 and disordered the numbering of them all. Fidelio exists in three versions because he could not make the opera work, and the revision history is a record of repeated failure: of all the lessons in this catalogue, it is the one that most usefully corrects the myth of effortless mastery. The genre demanded instincts, speed, delegation, compromise, that ran against his grain, and the finished Fidelio is a triumph of persistence over temperament, assembled across nine years from the wreckage of two public humiliations.

The 1814 production itself deserves its line in the record. It opened on 23 May at the Kärntnertortheater with Milder again as Leonore and Johann Michael Vogl, the great singing actor of the Viennese stage, as Pizarro, and the composer conducted, with the management taking the by then customary precaution of stationing Umlauf where the orchestra could also watch him. This time the machinery held. The opera was repeated through the summer to warm houses, travelled within two seasons to Prague and Berlin, and never again left the German repertory. Beethoven tinkered at its edges afterward and talked for years of new operas, on subjects from Macbeth to a Faust, but no second opera was ever begun in earnest. The catalogue’s operatic account closes with the work he had to write three times, which may be the most Beethovenian outcome imaginable: the genre he could not master at a stroke became the genre he conquered by attrition.

The incidental music and the occasional works

The catalogue’s margins hold a class of works written for occasions: theatre productions, ceremonies, namedays, congresses. Posterity has treated them as footnotes, but they paid bills, built relationships and occasionally produced music that outlasted the symphonies’ rivals for his contemporaries’ affection. The overture to Coriolan, Opus 62 of 1807, written for a tragedy by Heinrich von Collin, is the class’s acknowledged masterpiece, a portrait of Shakespeare’s Roman as Collin remade him, defiance and collapse compressed into a single movement that ends not in triumph but in disintegration, the theme audibly falling apart in the coda. The music for Goethe’s Egmont, Opus 84 of 1810, overture and entr’actes and songs for the Dutch patriot’s tragedy, gave the catalogue its most famous political overture after Fidelio’s: Goethe himself, the work’s severest imaginable judge, expressed his satisfaction with how the score had caught his play, and the Egmont overture entered the repertory as a free-standing emblem of resistance to tyranny.

The rest of the class is more uneven, and the works record should say so plainly. The Ruins of Athens and King Stephen, both written in 1811 for the opening of a new theatre in Pest, are pageant scores of local purpose, though the Turkish march from the Ruins escaped into independent fame. The Namensfeier overture, Opus 115, served an imperial nameday. The cantata Der glorreiche Augenblick, The Glorious Moment, Opus 136, was composed at speed for the Congress of Vienna in 1814, a celebration of the assembled monarchs that flattered its occasion and has rarely been revived since, an honest specimen of the genre’s built-in obsolescence. The oratorio Christ on the Mount of Olives, Opus 85 of 1803, belongs to the class by occasion, a Lenten concert commission, and escapes it by afterlife: through the nineteenth century, in the English-speaking world especially, it was among the most frequently performed of all his works, a fact the modern hierarchy of the catalogue finds almost as indigestible as the battle piece that follows. Occasional music is where a composer’s public actually lives, and Beethoven’s public, then as since, did not always live where his reputation eventually settled.

The margins reach further back than Vienna. The earliest orchestral music Beethoven wrote was occasional in the purest sense: the Music for a Ballet of Knights, WoO 1, composed in Bonn in 1791 for a carnival entertainment devised by Count Waldstein and performed under the Count’s name, so that the young composer’s first orchestral score circulated as his patron’s work. At the other end of the career stands the incidental music to Leonore Prohaska, WoO 96 of 1815, choruses and a funeral march for a tragedy about a girl soldier of the wars of liberation, music written for a play that was never performed, the ultimate occasional work, an occasion that failed to occur. Between those poles sits Germania, the patriotic chorus Treitschke commissioned for his Singspiel of 1814, sung in the theatre while the Congress danced. Taken together, the occasional works are the catalogue’s connective tissue, the record of a composer embedded in his city’s ceremonies from carnival to congress, and they make the inward turn of the final decade legible as what it was: not a temperament but a withdrawal, chosen late, from a public role he had filled for thirty years.

Wellington’s Victory and the problem it poses

In June 1813 the Duke of Wellington defeated the French at Vitoria in Spain, and Vienna, which had endured two occupations by Napoleon, received the news as a deliverance. Johann Nepomuk Maelzel, the inventor and showman who hovered at the edge of Beethoven’s life as a supplier of ear trumpets and mechanical marvels, proposed a celebration: a battle piece for his panharmonicon, a mechanical orchestra of his own construction, depicting the engagement in sound. Beethoven composed it, then scored it for a real orchestra when the machine proved impractical for the hall, and Wellington’s Victory, Opus 91, was premiered in that form on 8 December 1813, on the same benefit programme as the Seventh Symphony. Its two parts stage the battle and then celebrate it. The opposed armies are characterised by national tunes, the English by Rule, Britannia and the French by an old marching song, cannon and musket fire are written into the percussion parts as structural events, and the victory half builds a symphony of celebration on God Save the King, treated in counterpoint with a learnedness the occasion had not requested and the audience roared for anyway.

Now the fact that this article’s ladder of revelations reserves for this section, stated as plainly as it deserves. Wellington’s Victory, a battle piece written for a mechanical orchestral device, was the biggest public success of Beethoven’s career, far outselling the symphonies at the time. The December concerts were repeated by demand, the work was performed across Europe, the parts sold, arrangements multiplied, and the composer, who had earned modestly and erratically from two decades of masterpieces, made more from this piece in a few seasons than from most of the catalogue combined. The success then curdled into litigation: Maelzel claimed rights in the work, performed it abroad as his own property, and Beethoven answered with a public declaration and a legal fight that dragged on until a settlement years later. The inventor who had supplied the composer’s ear trumpets ended as his opponent in print, one of the sorriest episodes in the biography, and the battle piece went on earning without either of them.

The problem the piece poses is the reason it cannot be waved away, and this article will not wave it. The heroic account of Beethoven requires a composer indifferent to public taste, writing for posterity alone. The battle piece refutes the account in his own hand: he composed it with full craft, promoted it, fought for its profits and enjoyed its triumph, and its orchestral engineering, the spatial deployment of the bands, the build of the battle, the fugal celebration, is the work of the same musician who wrote the Seventh on the same programme. Lewis Lockwood’s treatment of the piece sets the terms a serious account has to accept: it is an accomplished occasional work whose success is a fact about its audience as much as about its composer, evidence of what public music was for in a city at war. The late works did not stop persuading because persuasion had been beneath him all along. He had been the most successful persuader in Europe. He stopped because the persuasion stopped being the point, and the battle piece, of all works, is what proves the stopping was a choice.

The Archduke Trio

The Piano Trio in B flat, Opus 97, composed in 1811 and dedicated to Archduke Rudolph, is the summit of Beethoven’s chamber music for the public world, and its premiere carries a biographical weight that the works record must register without dwelling on. Rudolph, younger brother of the Emperor, was Beethoven’s composition pupil, his most important patron and the dedicatee of more major works than any other individual, and the trio written for his circle is music of unusual spaciousness and ease, four movements of a breadth that assumes leisured, expert listeners. It was introduced on 11 April 1814 at a charity concert, with Schuppanzigh and the cellist Joseph Linke, and the composer at the piano. Spohr, who heard the performance, left the essential report: the piano was badly out of tune, the deaf composer played the loud passages with a violence that blurred them and the quiet ones almost inaudibly, and the occasion was at once a triumph and a leave-taking. It was Beethoven’s final public appearance as a pianist.

Rudolph is the thread that runs through the whole late catalogue, and the trio is where his role in the works record should be fixed. The Archduke was no ceremonial patron. He was a pianist of real attainment who studied composition with Beethoven for years, received the dedications of the Fourth and Fifth piano concertos, the Hammerklavier, the Missa Solemnis, the last piano sonata and the Grosse Fuge, and stood to the composer as pupil, protector and, in the economics of Viennese music, employer of last resort. The Opus 97 trio was written for performance in his orbit and first played in public by his musical household’s extended circle, and its ease is the ease of music written for listeners whose competence could be assumed. That assumption, the expert private audience, is precisely the one the late works would generalise. The Archduke Trio is the public body’s most gracious achievement and the private body’s unwitting prophecy, which is why this article gives it a section of its own among works twice its fame.

The trio itself breathes the confidence of a man summing up a genre. Its first movement moves at a pace no earlier trio attempts, its theme broad enough to support a movement of symphonic span in a drawing room. The scherzo plays with a chromatic slither in its middle section that looks forward to the wit of the late music. The slow movement, a theme with variations, finds the stillness that the late style would later make its home, and the finale dances the work out with a Hungarian colouring in its episodes. Around it, the chamber catalogue of the public years completes itself: the Harp quartet and the Serioso, the last violin sonata of 1812, and then the two cello sonatas of 1815, Opus 102, in which the easy address of the Archduke manner audibly tightens and darkens. Those cello sonatas are the bridge. After them, chamber music as public entertainment disappears from the catalogue for a decade, and when the string quartet returns, it returns speaking the private language.

The Hammerklavier sonata

The Piano Sonata in B flat, Opus 106, composed across 1817 and 1818 and dedicated to Archduke Rudolph, is the point where the piano music openly defects from the public body to the private one. Its nickname is a description before it is a compliment: Hammerklavier was simply the German word for the pianoforte printed on its title page, distinguishing the modern instrument from the harpsichord, and it attached itself to this sonata alone among his works because this sonata alone made the instrument’s full modern resources a condition of its sense. The first movement is built on a scale the early sonatas never contemplated, a vast sonata structure in which the themes are less melodies than blocks of harmony and interval, thirds and their inversions generating the argument from the opening bars. Beethoven, writing to its dedicatee as publication approached in 1819, predicted that the sonata would give pianists something to do and would be played in fifty years. The prediction was, for once, an underestimate of his own difficulty: the work remained a byword for the unplayable for generations, and its conquest by the concert platform is a nineteenth and twentieth century story.

The sonata’s architecture is a deliberate construction of extremes. The scherzo is brief, sly and sinister, a compressed parody of the first movement’s materials. The Adagio sostenuto that follows is the longest slow movement he ever wrote for the piano, a meditation of nearly twenty minutes in which a single grieving theme is ornamented, interrupted and finally dissolved into recitative, and which performers from his century to ours have treated as the summit of his keyboard writing. Then comes the finale’s gambit: a slow introduction of probing, dissonant improvisation, passages feeling their way through remote keys as if searching for a door, which opens at last onto a fugue of unprecedented scale and ferocity, marked to be played with some licences, its subject hurled through inversion, augmentation and stretto until the sonata ends in a blaze of learned violence. A fugue, the most rule-bound and least public of forms, closes the largest public instrument’s largest sonata, and it does so not as display but as necessity: after the Adagio’s grief, only counterpoint could rebuild the world. William Kinderman, whose studies of the sketchbooks trace this sonata’s long genesis in the composer’s workbooks, treats the Hammerklavier as the founding document of the late period, the work in which the procedures of the final decade, fugue, variation, the compression of opposites into single movements, are all announced at full scale. The works record agrees with the dating if not with every implication. The late period does not begin with the last sonatas or the last quartets. It begins here, in 1818, with a piano sonata nobody could play.

Its publishing history carries the same lesson in practical form. Beethoven sent the manuscript to London through his former pupil Ferdinand Ries in the hope of an English edition to match the Viennese one, and the two issues of 1819 differ in details that editors have been reconciling ever since, the London text preserving readings the Vienna print lost. Even the work’s tempo became part of its legend: the metronome mark he supplied for the first movement demands a speed so extreme that editors and performers have argued for two centuries over whether it is a misprint, a misreading of the device or a genuine instruction that only modern instruments and modern technique could finally approach. A sonata whose text, tempo and technique all remain contested is not a monument but an open file, and the Hammerklavier has functioned in the catalogue ever since as the standing proof that difficulty in Beethoven is never an accident of execution. It is the subject, stated once, at full scale, in the most public instrument he had.

The Diabelli Variations

In 1819 the Viennese publisher Anton Diabelli issued an invitation to the composers of Austria: each was to contribute a single variation on a waltz of his own composition, and the results would be published together as a patriotic album. Some fifty composers accepted, among them Schubert and the eleven-year-old Franz Liszt. Beethoven’s response dismantled the project. He first brushed the invitation aside, then became obsessed with the theme, and across four years, with a long interruption for the Missa Solemnis, he produced not one variation but thirty-three, a work so large that Diabelli published it separately in 1823 as Opus 120, a year before the collective album appeared with the single contributions of everyone else. The waltz he was given is a sturdy, ordinary, utterly unmemorable tune, and the disparity between the material and the result is the work’s founding joke and its deepest subject.

William Kinderman, whose 1987 monograph on the set remains its standard study, reads the thirty-three variations as a planned cosmos rather than an accumulation. The variations fall into groups that parody, deepen and finally transfigure their theme: there are variations that mock the waltz’s squareness, variations that turn it into a funeral march, a nocturne, a display of learned counterpoint, and one famous variation that quotes, with a wink the whole of Vienna could hear, a phrase from Leporello’s music in Mozart’s Don Giovanni. The sequence closes with a fugue of Handelian weight, after which the final variations do something no variation set had done: they let the theme go, dissolving through a slow, ethereal variation into a closing minuet in which Diabelli’s waltz returns transfigured, graceful, almost unrecognisable, like a acquaintance met in old age. Kinderman’s central claim, that the set enacts a comedy of the creative process itself, the journeyman tune educated into wisdom, has shaped all subsequent writing on the work.

The set’s genesis, which Kinderman’s sketch research reconstructed, deepens the joke into a parable of the whole late method. Beethoven drafted a sequence of twenty-three variations in 1819, set the work aside for the Missa Solemnis, and returned to it in the winter of 1822 and 1823 to add ten more, reordering the whole and reframing its ending, so that the published set is a work in two strata, the high spirits of 1819 enclosed in the architecture of 1823. Its dedication went to Antonie Brentano, the woman at the centre of the Brentano family circle to which so much of his intimate life was attached. A publisher’s advertising stunt had been intercepted, delayed by a mass, rebuilt over four years and issued as the largest piano work of the age, and Diabelli, to his credit, understood what he had accidentally commissioned and marketed the set as the masterpiece it was, placing Beethoven’s thirty-three variations at the head of his patriotic enterprise and letting the fifty single variations of everyone else follow as an appendix.

The Diabelli Variations are the private body at its most complete. They were written without a commission in any meaningful sense, without a dedicatee to please or a hall to fill, at the desk of a deaf man amusing and testing himself with the most disposable material his trade could offer. Alfred Brendel, the pianist who did more than any other modern performer to establish the work at the centre of the repertory, judged it the greatest of all piano works, and the judgment no longer reads as extravagance. A ranking of the catalogue that places the Diabelli set below the famous sonatas is ranking by celebrity. By the evidence of the score, thirty-three variations on a publisher’s waltz constitute one of the two or three largest structures Beethoven ever built, and they were built, pointedly, on nothing.

The last three piano sonatas

The final piano sonatas, Opus 109, Opus 110 and Opus 111, composed between 1820 and 1822, are the works in which the piano music completes the journey the Hammerklavier began. Opus 109 in E major, dedicated to Maximiliane Brentano, opens with a movement that alternates between flowing figuration and slow meditation at a compression earlier sonatas never attempted, the whole first movement gone in the time a Waldstein exposition takes to establish itself, and it closes with a theme and variations whose theme is a hymn, varied from intimacy to a climax of trills and cascading sound in which the theme itself dissolves into its own ornamentation. Opus 110 in A flat has no dedication and the strangest design of the three: a serene opening movement, a terse scherzo, and a finale that alternates a lamenting arioso with a fugue, the fugue collapsing midway into exhaustion, the score’s own markings charting a voice spent and then, in one of the catalogue’s great acts of recovery, gradually reviving until the fugue returns inverted and drives the sonata home in triumph.

Opus 111 in C minor closes the sequence and the genre. It has two movements. The first is a maelstrom of defiance, a sonata allegro of compressed violence whose slow introduction reaches back across the whole career to the Pathétique’s grave opening chords and finds them darker. The second is a set of variations on a theme of disarming simplicity called the Arietta, in which the variations progressively subdivide the beat until the theme seems to hang suspended in a shimmer of trills, as if rhythm itself were being laid down. The missing third movement has generated more commentary than many complete sonatas. The early tradition explained it by anecdote, but the durable explanation is the one the novelist Thomas Mann gave the work in Doctor Faustus in 1947, where his fictional lecturer Wendell Kretzschmar asks why Beethoven wrote no third movement and answers that after the Arietta’s farewell, a return to the world of the sonata would be impossible: the work has not omitted its finale but transcended the need for one. Mann’s scene is fiction standing on analysis, and Kinderman’s studies of the sonata’s sketches supply the analysis in documentary form, showing a structure planned as a dyad from its early drafts. The trilogy also repays attention to its middle surfaces, where the private manner hides in plain sight. The scherzo of Opus 110 stitches its theme from two Viennese street songs its first hearers would have recognised from the gutter and the fairground, a deliberate descent into the vernacular inside the most inward of the three works, as if the sonata were remembering the city’s noise on its way inward. Opus 109 opens its finale with a theme the score marks to be played in a singing manner, and then subjects that hymn to variations of increasing rhythmic fragmentation, until the theme’s return at the end feels like a recollection rather than a repeat. Opus 110’s lament, its arioso, is marked to be played with grief in the composer’s own performance directions, an emotional instruction of a directness the early sonatas never risked. These are works that speak in the first person, in a genre that had begun, in Opus 2, speaking the most public language a young composer could command.

The last sonata was always going to have two movements. The sonata as a form, in Beethoven’s hands, had arrived at the point where addition had become subtraction, and the series of thirty-two that had begun in the shop window of Opus 2 closed in a room with almost nobody in it.

The Missa Solemnis

The Missa Solemnis in D major, Opus 123, was begun in 1819 for a specific public occasion, the enthronement of Archduke Rudolph as Archbishop of Olomouc, and it missed the occasion by three years. Beethoven announced the work for the ceremony of March 1820 and then kept writing until 1823, studying the church music of earlier centuries as he went, Palestrina and the modal polyphonists and Handel’s oratorios open on his desk alongside the liturgy, until the mass had grown from an act of homage into the most demanding score of his life. He knew what it was. His correspondence with publishers during its long gestation describes it, without his usual salesman’s irony, as the greatest work he had yet written, and when composition ended he conducted an extraordinary campaign to place it: before any printed edition, manuscript copies were offered by subscription to the courts of Europe at fifty ducats each, and copies went out under his seal to kings and princes, a distribution model borrowed from the eighteenth century for a work that the nineteenth could barely perform.

Its first complete performance took place not in Vienna but in St Petersburg, on 7 April 1824, under the patronage of Prince Nikolai Galitzin, the Russian nobleman who had also commissioned the first of the late quartets. Vienna heard three of its movements a month later, at the concert that introduced the Ninth Symphony, where the Kyrie, Credo and Agnus Dei were billed discreetly as hymns because the theatre’s licence forbade church music on its stage. The work the Viennese sampled that night runs to some eighty minutes in full. Its Gloria ends with a fugue of Handelian scale. Its Credo builds a cathedral of counterpoint around the central mysteries of the text and depicts the resurrection with a suddenness that still startles. Its Sanctus contains a solo violin obbligato, the Praeludium, in which a single instrument descends through the texture like the presence the words invoke, and its Agnus Dei closes the mass with a prayer for peace that is twice invaded by military music from outside, trumpets and drums of a war the prayer cannot keep out, before the voices win an uneasy quiet.

Where does the Missa sit in the two bodies? It is the catalogue’s great border case, and this article has placed it between them deliberately. In form it is the most public of works, a mass for an archbishop’s enthronement, festal, choral, architectural. In address it is private to the point of intransigence: its vocal writing makes demands that professional choirs still approach with respect, its lengths ignore every convention of liturgical utility, and its composer dedicated the score to Rudolph with an inscription stating that it came from the heart and wished to go to the heart, a transaction between two people conducted in the largest available medium. Beethoven’s own ranking of it was unambiguous, and posterity’s has been perpetually unsettled, which is itself a datum.

The subscription campaign is worth one more line of the record, because it shows the private body’s economics operating at the largest scale. Roughly ten courts and connoisseurs subscribed, among them the King of Prussia and the Russian court through Galitzin, and each received a hand-copied score under seal, with readings that differ in small ways from the edition Schott finally printed at Mainz in 1827. The work thus entered the world the way a Renaissance mass had, as a set of presentation manuscripts for named patrons, three years after its composer had completed it and in the lifetime of the symphony that shared its desk. No other work in the catalogue was distributed like a relic before it was published like a book, and the doubleness of that distribution, relic and book, court object and concert problem, is the Missa’s identity in the record as much as any bar of its score. The Missa is the work a ranking can least afford to place by reputation. It has to be placed by encounter, and the encounter is overwhelming in proportion as the listener brings to it the patience the public works never required.

The Ninth Symphony

The Symphony No. 9 in D minor, Opus 125, occupied Beethoven in earnest from 1822 to the early months of 1824, but its seed is the oldest documented intention in the whole catalogue. In January 1793 a correspondent in Bonn reported to a friend of Friedrich Schiller that the young Beethoven intended to set the poet’s ode on joy, strophe by strophe, and the intention then waited thirty years for its hour. Sketches for a D minor symphony accumulate from 1817 onward, interleaved with the Missa Solemnis in the same workbooks, and the London Philharmonic Society’s commission of 1822, with its offer of fifty pounds, supplied the external occasion for a design that had long been forming. The work that resulted is scored for the largest forces he had yet assembled and runs for well over an hour, and it ends by doing the thing the symphonic tradition had flirted with and never dared: after three purely orchestral movements, it stops, reconsiders itself, and starts again with voices.

The finale’s construction is the most audacious piece of dramaturgy in the catalogue and repays a plain description. It opens with a dissonant outburst, a chord of accumulated violence that later writers named the terror fanfare, and the cellos and basses answer it in a passage shaped exactly like operatic recitative, speech without words. The themes of the three preceding movements are then paraded in turn, and each is cut off by the low strings’ recitative, rejected as inadequate to what the symphony still has to say, until a new theme, quiet and hymn-like, is proposed, accepted, and built in the orchestra alone into a complete statement. Only then does a solo voice enter, with a few opening words of Beethoven’s own rather than Schiller’s, setting the poem aside for one sentence to call for an end to the sounds of struggle and the adoption of a more joyful tone. What follows is a vast structure in movements within the movement: the hymn sung and varied, a march episode in a different metre with a tenor solo and the orchestra’s percussion section imitating a military band, a double fugue welding two themes into one argument, and a closing sequence that alternates rapture with acceleration until the whole apparatus burns out at speed.

The finale had rehearsals inside the catalogue itself. In 1808, at the frozen December concert that introduced the Fifth and Sixth symphonies, Beethoven had closed the programme with a Choral Fantasy for piano, orchestra and chorus, composed at speed for the occasion, in which a theme played first by the piano alone is gradually clothed by the orchestra and finally crowned by voices: the Ninth’s finale in embryo, sixteen years early, down to the family resemblance between the Fantasy’s theme and the ode melody. That melody has its own ancestry, since its contour reaches back to a song of mutual love he had written in 1795, as if the tune the symphony elects, after rejecting its own first three movements, were one the composer had been carrying since Bonn. Nicholas Cook, whose Cambridge handbook on the symphony remains the standard short study, reads the finale not as a solution but as a question the work poses to itself about its own materials, and the reading explains the movement’s durability better than any celebration does. The Ninth is the largest public work in the catalogue and the summit of the public body, a symphony that addresses not a room but an abstraction, mankind, and yet its machinery is theatrical, even operatic: recitative, rejection, entrance, proclamation. The public body had begun, in the First Symphony, with a single chord pointing the wrong way. It ends with a chorus of hundreds telling the audience that the symphony’s subject is the audience itself.

The premiere and what the audience heard

The Ninth was nearly premiered in Berlin. Beethoven, convinced that Viennese taste had been captured by Italian opera and that Rossini’s shadow lay across his own city, opened negotiations to introduce the symphony and the Missa excerpts in the Prussian capital, and Vienna learned of the plan with alarm. In February 1824 a remarkable document arrived at his rooms: an address signed by some thirty of the city’s leading musicians, publishers and patrons, begging him not to deprive Vienna of the works and promising a public worthy of them. He yielded, with conditions, and the Great Academic Concert was announced for 7 May 1824 at the Theater am Kärntnertor. The programme placed the overture The Consecration of the House at the head, then the three movements of the Missa disguised as hymns, then the new symphony. The soloists were the eighteen-year-old Henriette Sontag, already a star, and Caroline Unger, with the tenor Anton Haizinger and the bass Joseph Seipelt. Michael Umlauf conducted in fact. Beethoven stood beside him with the score, beating his own tempo, having instructed that the orchestra watch Umlauf, since the deaf composer beside the podium could no longer hear what he was directing.

Two rehearsals had to suffice for the largest concert of the decade, and the standard account of the evening, assembled from the reports of those present, records a success that was genuine and ragged at once. The scherzo provoked an ovation in mid-performance, applause that broke the court’s rules on when a work might be interrupted, and at the end the house rose in a storm of clapping and waving handkerchiefs. Beethoven, still turning the pages of his score and beating time to a tempo of his own, did not know it had finished until Caroline Unger took him by the arm and turned him to face the audience, a moment every biography repeats because every witness remembered it. The second performance, on 23 May, told the economic truth behind the triumph: the house was barely half full, the day was fine, the city was at its excursions, and the composer, who had expected the concert to repair his finances, came away disappointed and distributing blame.

The address that had kept the premiere in Vienna deserves its place in the works record too, because it shows the reputation acting as an asset. Its signatories, publishers, aristocratic patrons and fellow musicians, framed their plea as a public obligation: the city that had formed the composer owed Europe the first hearing of the works on which his fame would rest, and the withdrawal of the premiere to Berlin would read as Vienna’s failure rather than his. Beethoven, who had genuine grievances about Viennese taste and Rossini’s ascendancy, kept the document among his papers, and its flattery was underwritten by the practical terms he extracted: the largest theatre, the best available soloists, and billing that placed three movements of the unfinished mass beside the symphony as the twin summits of his art. The paperwork of the premiere, petition, programmes, the disguised hymns, the doubled conductors, is the fullest surviving picture of how a masterwork entered the world before the age of the recording, half ceremony and half improvisation. Both evenings belong in the works record. The Ninth conquered its first audience and failed to pay its rent in the same month, and the gap between those two facts is the precise shape of the late public career: the reputation was now European, and the market for it, in the city where it had been made, remained a village market of single nights.

The late quartets as a group

The last chamber works form a group with their own commission, their own calendar and their own legend, and they are best introduced together before the strangest of them is taken apart. In November 1822 Prince Nikolai Galitzin, a Russian nobleman and amateur cellist, wrote to Beethoven asking for one, two or three new string quartets at the composer’s own price. Beethoven named fifty ducats apiece, and the commission produced, across 1824 to 1826, the quartets Opus 127 in E flat, Opus 132 in A minor and Opus 130 in B flat. Two more followed from other hands and his own momentum: Opus 131 in C sharp minor and Opus 135 in F major, and the Grosse Fuge, detached from Opus 130, counts as a sixth late quartet movement of independent standing. Together they amount to some five hours of music for four instruments, composed in the last thirty months of his life alongside nothing else of consequence, and they constitute the private body of the catalogue in its purest form.

Their designs refuse every convention the Razumovsky quartets had already stretched. Opus 130 has six movements, including a tiny Presto, a German dance and a Cavatina of such concentrated songfulness that the composer, by the testimony of the players who knew him, was moved to tears by his own movement. Opus 131 has seven movements and is played without a single full stop between them, fugue, variations, scherzo and slow movement flowing in one continuous span of some forty minutes; Wagner, reporting the judgment of the quartet’s first players, recorded that Beethoven considered it his greatest quartet. Opus 132 contains the group’s most famous slow movement, written after his recovery from a serious illness in the spring of 1825 and headed in the score as a convalescent’s holy song of thanksgiving, composed in an archaic church mode and alternating, section by section, with music marked as a feeling of new strength returning. These are works that assume performers who will live with them for months and listeners who will return across years. Their first audiences were drawing rooms. Opus 127, premiered by Schuppanzigh on 6 March 1825, was even judged a failure at its first hearing because the players had not yet mastered it, and a rival quartet under Joseph Böhm had to demonstrate, weeks later, what the work actually contained.

One passage inside the group concentrates everything the works record needs to say about their emotional range. The Cavatina of Opus 130, its fifth movement, is an aria for the first violin of sustained, songful grief, and at its centre the score directs a passage to be played in a manner the composer marked with a word meaning oppressed or stifled, where the violin’s line breaks into short, gasping figures over a held chord, as though the song had forgotten how to breathe. The quartet’s first cellist, who knew the composer well, reported that the movement cost Beethoven tears in the writing and that he himself could never hear it unmoved. A composer whose public music had specialised in command ends his quartet cycle writing instructions for suffocation into a slow movement, and the marking, a stage direction for an emotion, has no precedent in his earlier chamber music. The private body did not merely think differently. It felt at a different resolution, and it trusted four players in a room to transmit what the largest orchestra in Europe could not have been asked to carry.

It is in this group that the third question of this article opens, and it opens on the finale of Opus 130. When that quartet was first performed in March 1826, its last movement was not the light finale the work now ends with but a fugue of a size and ferocity no quartet had ever carried. Why was the most radical movement he ever wrote removed from the work it belonged to? The question belongs to the next section, and its answer involves a publisher, a fee, and a dying man’s clear-eyed judgment about the difference between a quartet and a monument.

The Grosse Fuge and the movement that was replaced

What is the Grosse Fuge?

The Grosse Fuge is a single vast movement for string quartet, a double fugue of extreme dissonance and concentration composed in 1825 as the finale of the Quartet Opus 130. Beethoven later detached it, wrote a replacement finale for the quartet, and published the fugue separately as Opus 133.

The movement itself must be described before its removal can be understood. It opens with a slow proclamation of its subject in bare octaves, stated four ways, like a theorem being announced in four formulations, and then detonates into a fugue of relentless contrapuntal pressure, in which the subject is inverted, augmented, fragmented and driven through remote keys at a rhythmic violence that still startles players. A gentler contrasting fugue offers temporary shelter before the storm resumes, and the whole movement, lasting about a quarter of an hour, demands of four string players the stamina of an orchestra and the precision of a clock. At the premiere of Opus 130 on 21 March 1826, Schuppanzigh’s audience applauded the quartet warmly and demanded repeats of two of its inner movements, but the finale stood outside their comprehension. One Viennese reviewer confessed it as impenetrable to him as a foreign language. Beethoven, informed of the reaction, was characteristically unrepentant about the movement and characteristically shrewd about the work: the fugue, he is reported to have growled, was the movement the others would be forgotten for.

What happened next is documented, and the documentation matters because the romantic version, a genius browbeaten into retreat, is false. The publisher Matthias Artaria, who had the quartet in production, took the commercial view that the finale made the work unsellable, and conveyed through Karl Holz, the quartet’s second violinist and the composer’s close associate in those years, a proposal: publish the fugue separately, as its own opus, and supply the quartet with a new finale. Beethoven agreed, in the autumn of 1826, and the terms of his agreement show a man managing his property rather than surrendering his art. He composed the replacement finale in November 1826, at Gneixendorf in the country, while his health was collapsing around him; it is the last music he completed. He prepared a piano duet arrangement of the fugue himself, published as Opus 134, to widen its market. The fugue itself appeared as Opus 133 in May 1827, some weeks after his death, dedicated to Archduke Rudolph like so much of the late work. And here the last rung of this article’s ladder can be set down: he removed the Grosse Fuge from its quartet and wrote a replacement finale, which means the most uncompromising music he produced was taken out by his own decision, taken out, moreover, with its value asserted in the very act, since the price of the removal was separate publication under its own number, in two formats, with a dedication to an archduke. The motives were commercial and artistic at once and are recorded as such. A quartet with the fugue was a monument nobody could sell. As two works, a quartet and a fugue, both could live. Posterity, which performs the fugue constantly and the replacement finale dutifully, has spent two centuries quietly voting on whether he was right, and the vote, as the reception sections ahead will show, remains delightfully unsettled: the fugue is now the famous one.

The final quartet and the last complete movement

The String Quartet in F major, Opus 135, completed at Gneixendorf in October 1826, is the slightest of the late quartets by design, four movements at the scale of Haydn, as if the composer who had expanded every form he touched had decided to close the quartet series by demonstrating that he could still be brief on purpose. Its slow movement is a set of variations of extraordinary stillness, music that seems to breathe more slowly than the room around it, and its finale is prefaced in the manuscript by a motto, a grave question about whether a thing must be and its own emphatic answer, borrowed from a joke of the composer’s household: his friend Ignaz Dembscher had once queried a subscription payment with the same question, and Beethoven had already teased him in a canon on the words. The joke became the last quartet’s portal, and the movement it introduces treats the question with a weight that turns the joke profound, struggle giving way to a finale of Haydnesque wit. The quartet was first performed in March 1828, almost exactly a year after the composer’s death, on a memorial programme in Vienna.

The last complete movement Beethoven wrote, however, is not in Opus 135. Chronology, that unreliable narrator throughout this catalogue, saves its final irony for the end: the replacement finale for Opus 130, composed in November 1826 after Opus 135 was finished, is the last piece of music he completed. It is a graceful, dancing rondo of no great length, lighter in every way than the movement it displaced, and it closes Opus 130 in most performances. Around it, in the same final months, lie the remains of the Tenth Symphony, the sketches Barry Cooper would one day assemble, and the plans for works that exist only as entries in conversation books. The catalogue ends, then, not with a peroration but with an act of practical craftsmanship, a working composer supplying a performable ending to a quartet so that the quartet could be sold, while the movement it replaced waited in its own opus number for a century that could play it. He died in Vienna on 26 March 1827, and the works record closes with the symmetry the whole article has been tracing: the public body and the private body finished within weeks of each other, one in a movement written to be enjoyed, the other in a movement written to be survived.

Opus 135 itself made its way into the world in the order the late works had taught their publishers to expect: print first, performance afterward. Schlesinger issued it in 1827, and for two generations it served as the gentlest available door into the late quartets, the one whose scale a Haydn-formed listener could grasp, before its companions’ difficulty had been normalised by the Joachim Quartet and its successors. Its lightness was long held against it, as the Eighth Symphony’s had been, on the theory that the last works should sound like last works. The works record should register the pattern by now: in this catalogue, the light final pieces are not relaxations of intent but changes of it, and the F major quartet’s composure, like the F major symphony’s wit, is an achievement of engineering that only looks like ease. A catalogue that closes twice, once in a rondo and once in a fugue, has in effect declined to close at all, and the reception history that follows is the story of listeners deciding, generation by generation, which ending to believe.

Reception then: what succeeded immediately

The lifetime reception of the catalogue drew a map almost opposite to the modern one, and reconstructing it honestly is the necessary groundwork for any ranking. The works that conquered immediately were the works of access. The Septet, Opus 20, published in 1802, was for years the most popular piece he had written, performed everywhere and arranged for every combination, to the point where its composer grew to resent the shadow it cast. The Pathétique and the sonata posterity calls Moonlight sold in edition after edition. The Seventh Symphony and Wellington’s Victory made the winter of 1813 and 1814 the season of his greatest public glory, and the Congress of Vienna, gathering in the autumn of 1814, found him installed as the musical emblem of the victorious coalition’s capital, fêted by the very courts that had paid for the Missa subscriptions a decade later. The Fidelio of 1814 succeeded at last and stayed in the repertory, and Christ on the Mount of Olives carried his name through the choral societies of Britain and America for generations.

Against that, set the failures and the slow burns. The Eroica divided its first critics and was granted its length only grudgingly. The violin concerto failed outright and vanished. The Razumovsky quartets were judged incomprehensible in print. The 1808 Akademie that introduced the Fifth and Sixth was remembered for years chiefly as an endurance test in a frozen hall. The Ninth’s second performance played to empty benches. The late quartets were barely performed at all, and when the composer died in March 1827, the works by which the European public principally knew him were the Septet, the battle piece, the middle symphonies, the famous sonatas and Fidelio, a list on which the Diabelli Variations, the Missa Solemnis and the late quartets do not appear. London, which had never heard him play, understood his stature as clearly as Vienna did: the Philharmonic Society that had commissioned the Ninth sent him a gift of one hundred pounds on his deathbed, an act of international professional respect that reached him through the pianist Ignaz Moscheles in his final weeks. The reputation was real. It was simply attached, in large part, to different music than the reputation that exists now, and the transfer of attachment from one body of work to the other is the story the next section has to tell.

One mechanism of the lifetime fame is easy to miss from a concert-centred age: most Europeans who knew the symphonies knew them at a piano. The works circulated in arrangements for piano solo, piano duet and small chamber combinations, published in quantity and played in parlours from London to St Petersburg, so that the Eroica and the Seventh were domestic possessions years before most of their owners heard an orchestra play them. The official honours travelled by the same post as the subscription scores. In 1824 the King of France returned his Missa copy’s courtesy with a heavy gold medal bearing his portrait, an honour Beethoven showed to visitors with undisguised pleasure. The fame, in short, was neither local nor fragile. It was a European distribution network of print, arrangement and courtly exchange, and the works it carried most efficiently were the ones a parlour could play.

Reception since: what rose and what fell

The transfer began in the concert halls of the generation after his death. In Paris, François-Antoine Habeneck’s Conservatoire concerts from 1828 onward drilled an orchestra in the symphonies until they became the centre of the French repertory, and Berlioz’s criticism carried the campaign into print. In Dresden in 1846 Wagner conducted the Ninth and published his reading of it, fixing the symphony’s status as the century’s scripture and its finale as the doorway through which music’s future had to pass. The piano sonatas underwent a parallel canonisation as the literature by which every serious pianist was formed, the keyboard’s equivalent of a classical education. Fidelio acquired a moral centrality in German-speaking theatres that outlasted changes of regime, the opera a nation reached for when it wished to stage its own rescue from tyranny, most famously when the Vienna State Opera reopened its rebuilt house with it in 1955 under Karl Böhm, five months after the occupation of Austria finally ended.

What fell is as instructive. Wellington’s Victory slid from universal favourite to embarrassment within fifty years, and by the twentieth century it was the work admirers apologised for and detractors quoted, the exact inversion of its lifetime standing. The occasional works went with it. Christ on the Mount of Olives, once among his most performed scores, dwindled to a curiosity. The Missa Solemnis rose in prestige while remaining unperformed in any ordinary sense, a masterpiece certified by difficulty: Theodor W. Adorno’s celebrated essay of 1959 treats it as a work at war with its own genre, alienated from the liturgy it sets and from the symphonic conventions it borrows, and the argument itself became a form of canonisation. The late quartets rose slowest and furthest. Cherished first by players, the Joachim Quartet above all, then fixed in the gramophone era by the Busch Quartet’s recordings of the 1930s, they completed their journey from unsellable to supreme in the middle of the twentieth century, and the Grosse Fuge travelled with them, Stravinsky judging it a work that would remain contemporary in every age. What composers, as distinct from audiences, took from all this is another article’s territory, and it is treated in the account of Beethoven’s influence on music. The Ninth acquired the strangest institutional afterlife of all: in 1972 the Council of Europe adopted its great theme, in an arrangement by Herbert von Karajan, as the anthem of Europe, and in December 1989 Leonard Bernstein conducted the symphony in Berlin to celebrate the fallen Wall, altering the poem’s central word in performance to the German word for freedom, a liberty with the text that only the work’s status as public property could license.

Scholarship kept pace with the ceremonies. The bicentenary year of 1970 was marked by the first complete recorded edition of the works, a monument of the gramophone age that treated the catalogue, for the first time in its history, as a single object that could be owned entire, while the modern critical edition of the complete works, published by Henle in Munich from 1961 onward, slowly replaced the nineteenth-century texts with readings built from the autographs, the sketchbooks and the copyists’ scores. The works article and the works themselves converged in that project: to know what Beethoven wrote became, at last, a soluble problem, even where knowing what it means was not. The reception since is therefore not only a story of taste rising and falling. It is a story of access, each generation’s Beethoven rebuilt from the materials that generation could obtain, and the transfers of attachment that followed were as much the work of publishers, record companies and editors as they were of listeners.

A listening order for a newcomer

Which Beethoven work should I listen to first?

The Seventh Symphony. It asks nothing in advance, no programme, no text and no patience with unfamiliar forms, and it demonstrates the essence of the public Beethoven, rhythm organising an entire structure, inside forty minutes. A listener who loves it is ready for the Fifth, the Eroica and the whole catalogue in the order this article gives.

The order proposed here is built on one principle: alternate the bodies, and let each work teach the skill the next one requires. After the Seventh, take the Pastoral, which teaches duration and quiet, and then the Fifth, whose four-note cell will now sound like what it is, a drama rather than a motto. The Pathétique and the Appassionata follow naturally, the public piano at its most direct, and then the Eroica, with the torn title page in mind and an hour set aside for it, because the Eroica is where the catalogue’s scale changes and the listener’s expectations must change with it. The Emperor Concerto and the Violin Concerto come next, the public virtuoso works, and with them the Archduke Trio, where the same address is made in a drawing room. Fidelio belongs after the symphonies if a staged performance is possible and after the concertos if it is not, since the opera’s three versions reward a listener who already knows what its composer sounds like when he is not fighting a libretto.

The second half of the order crosses into the private body by the shallowest fords. Begin with the last sonatas in reverse order of difficulty: Opus 110 first, for its aria of lament and its fugue that falls and rises, then Opus 109, then Opus 111, whose two movements will now register as a destination rather than an oddity. The first Razumovsky quartet makes the bridge to the quartets, and the listener who has come this far is ready for the Missa Solemnis, taken in one sitting with the text of the mass open in translation and no other demand on the evening. The Hammerklavier and the Diabelli Variations follow, the two great keyboard structures, and the late quartets come last, Opus 132 before Opus 131, the Grosse Fuge saved for the very end of the journey, where it belongs: it is the work this catalogue’s first audiences could not hear, and hearing it last, with the whole output behind it, is the closest a modern listener can come to the experience of the century that learned to hear it. Two disciplines make the order work. The first is repetition: no work in the sequence should be heard once and filed, since Beethoven’s effects are structural and declare themselves on the second and third encounters, when the memory knows where the development is going and can attend to how it gets there. Hear each major work at least twice before advancing, and return to the Fifth and the Eroica at the end of the journey, when the late works have retuned the ear, because both will sound like different compositions. The second discipline is contrast of medium: alternate the recordings with a score where one can be had inexpensively, since following even a few pages of the quartet writing while it sounds converts the private body’s density from a blur into an argument. The order itself is a ladder, not a canon. A listener who stalls at the Hammerklavier for a month has not failed the sequence but understood it, and the listener who reaches the Grosse Fuge and dislikes it has reached the same frontier its first audience reached in 1826, with the whole catalogue behind them as evidence.

Readers who work through a sequence of this length over months often keep a listening diary alongside it, and the offline encrypted notes app obtained from the VaultBook download page suits a notebook of that kind, since the notes remain on the reader’s own machine and under the reader’s own key.

Why the late works stopped persuading

The thesis of this article can now be stated in its final form. Beethoven’s catalogue contains two bodies of work with different ambitions because persuasion is a technology with requirements, and the late works progressively lack them. A public work models its audience: it assumes listeners gathered once, in real time, who must be seized, held and released satisfied, and every device of the public body, the hammered motif, the engineered climax, the finale built like a peroration, serves that single encounter. The late works assume a different reader entirely: a performer alone with a score, a quartet willing to rehearse for months, a listener who will return. Their forms follow the assumption. Variation and fugue, the late style’s twin engines, are not rhetorical forms at all. They are forms of sustained attention, procedures for thinking about material in the presence of nobody, and the catalogue’s centre of gravity shifted to them as the concert room receded from its composer’s life.

The causes are documented and need no mythology. Deafness removed the feedback loop between platform and desk, ending the career as a performer that had shaped the public works from inside. The market shifted under him too: the late works were sold to publishers as scores, addressed to readers as much as to audiences, and their dedicatees were connoisseurs, an archduke who was his pupil, a Russian prince who played the cello, men who could be imagined at the desk rather than in the stalls. Even the commercial facts align. The persuading works had paid in applause and filled halls; the late works paid in subscription fees, publisher’s honoraria and esteem among professionals. He stopped persuading, in short, because nothing in his situation any longer required it and everything in his material invited the alternative.

One refinement keeps the thesis honest. The late works stopped persuading audiences, but they never stopped persuading altogether: they persuaded performers, publishers and princes, the intermediaries through whom posterity would meet them, and the removal of the Grosse Fuge shows the machinery of persuasion still switched on, aimed at a different target. A work can renounce the hall and still negotiate fiercely for its future. The late quartets were published, dedicated, priced and standardised in print with a care their composer lavished on nothing else in those years, and the bet embedded in that care, that readers and players would come who could meet the music on its own ground, is the one wager of the public career that was placed entirely on the private body’s behalf. The wager’s winnings are the modern listener’s inheritance. The audience the late works assume, patient, literate and willing to return, did not exist in 1826 in any number. It exists now, and it was created, in large part, by the works themselves.

What would have to be true for the older reading, the late works as decline, to stand? The sketchbooks would have to show a failing hand, and they show the opposite, a density of labour that increases as the works grow stranger. What would have to be true for the modern reading, the late works as the summit, to stand? Performers of the first rank would have had to adopt them as the centre of their art, and across the twentieth century they did. The two bodies therefore keep both their claims, and the ranking this article has been building resolves into a division of honours rather than a single list: the public works built the reputation and remain the door, and the late works are where the music stops trying to persuade an audience and becomes, instead, the record of a mind in conversation with itself. The catalogue that began with an erased name on a title page ends with works that need no name above them at all. Where their composer stands among the greatest composers of all time is a different argument, and the series reserves it for its own ground.

Frequently Asked Questions

Q: What are Beethoven’s most famous works?

The famous core of the catalogue is easily listed: the Fifth and Ninth symphonies, the Eroica, the Pastoral and the Seventh, the Emperor and Violin concertos, the Pathétique sonata and the sonata known as the Moonlight, the opera Fidelio, and, among the unnumbered works, the short piano bagatelle known as Für Elise, which may be the most played piece of all. Fame in this catalogue is not a reliable guide to scale or significance. The list mixes a forty-minute symphony with a piano piece of three minutes, and it omits almost the whole late body of work, the Missa Solemnis, the Diabelli Variations and the final quartets, which musicians and scholars place at the summit. The famous works are the door into the catalogue. They are not the whole house, and a works survey exists to show what stands behind them.

Q: What is an opus number?

An opus number is a work’s position in the sequence of a composer’s authorised publications, assigned by publishers as pieces appeared in print. Beethoven’s sequence runs from the three piano trios of Opus 1 in 1795 to the String Quartet Opus 135 of 1826. The number records a publishing event, not a date of composition, and the two can drift far apart: the two sonatas of Opus 49 were composed a decade before they were published. A single number may also hold a set rather than a work, so Opus 18 contains six quartets and Opus 2 contains three sonatas, while Opus 130 contains one quartet. Works that Beethoven never placed in the sequence, songs, dances, occasional pieces and early essays, were catalogued in the twentieth century under the abbreviation WoO, meaning works without opus number.

Q: How many works did Beethoven write in total?

Any single figure conceals a decision about what counts as a work. The publications carrying opus numbers run to 138 entries, but many entries are sets, so the individual pieces inside them, quartets, sonatas, trios and songs, number well beyond three hundred. Adding the unnumbered side of the catalogue, the pieces Georg Kinsky gathered as WoO, brings in several hundred more: songs and folk song settings, dances, canons, marches, occasional cantatas and the early concerto of 1784 whose orchestral parts are lost. Beyond the complete works lie the fragments and the sketchbooks, thousands of pages in which works were begun, abandoned or cannibalised, including the substantial remains of a Tenth Symphony. The honest answer is therefore a range with its reasoning attached: several hundred finished works, inside a paper trail far larger than the finished output, and no total that does not state its units.

Q: What makes the Eroica a turning point?

Duration and proportion, more than any single chord or theme. The Eroica, composed in 1803 and 1804, runs close to fifty minutes, about twice the length of the symphonies Beethoven inherited, and its first movement alone is longer than some complete earlier symphonies, with a development section that becomes the centre of gravity of the whole design and introduces material not heard before. Around that structural expansion the work gathers new content: a funeral march at the centre of a symphony, a finale built on a theme from a ballet about Prometheus, and a dedication first offered to a living political hero and then withdrawn, so that the symphony’s subject became heroism itself rather than a man. Its first reviewers admired the power and deplored the proportions in the same paragraphs. Every ambitious symphony written afterward had to reckon with the space it had opened.

Q: Why is the Fifth Symphony so widely known?

The Fifth begins with the most retainable gesture in orchestral music: four notes, three short and equal on one pitch and a fourth falling and held, a rhythm a listener can carry away after a single hearing and recognise for life. Behind that door stands an exceptionally legible design, four movements grown from the same rhythmic cell, a scherzo that returns like a ghost inside the finale, and a slow emergence from C minor darkness into a C major blaze reinforced by trombones for the first time in a symphony. Criticism launched it early: E. T. A. Hoffmann’s review of 1810 placed it among the most significant works of the age. Broadcasting completed the work, and the opening rhythm acquired a second life in the Second World War when its pattern matched the Morse signal for the letter V and the BBC built broadcasts around it. Fame of this order is an accumulation, not an accident.

Q: Is the Sixth Symphony programme music?

Partly, and the partition is the composer’s own. Each of the Pastoral’s five movements carries a descriptive heading, a scene by a brook, a peasants’ dance, a storm, and the score contains frankly illustrative touches, bird calls assigned to named instruments at the end of the brook movement and a storm of genuine violence in the fourth. Yet Beethoven presented the work as a recollection of country life understood as the expression of feeling rather than painting, and the music honours the qualification: the brook movement is a quarter of an hour of slow harmonic drifting whose effect depends on nothing depicted, and the storm functions as the interruption that gives the finale’s thanksgiving its occasion. Later programme music would attach detailed narratives to orchestral works. The Sixth offers scenes and states instead, which is why it became the standard exhibit in the nineteenth century’s argument about how much of the world music should try to carry.

Q: What happened at the violin concerto premiere?

The premiere, at the Theater an der Wien on 23 December 1806, was a benefit concert for the soloist, Franz Clement, the orchestra’s leader and one of the most admired violinists in Europe. By contemporary report the concerto reached him barely finished, and he played substantial stretches of the solo part at sight. The evening’s shape then conspired against the work: between its first movement and the remainder, Clement entertained the audience with a display piece of his own, performed on a single string with the violin held upside down, and a concerto of long, serene spans, which asks its soloist to float above the orchestra rather than dazzle it, stood little chance amid the entertainment. The reviews were cool and the work fell silent. It slept until May 1844, when the twelve-year-old Joseph Joachim performed it in London with Mendelssohn conducting, and that second premiere established it permanently.

Q: Why did Beethoven revise Fidelio?

Because the opera failed in the theatre twice, for reasons he could identify and believed he could fix, and because its subject, a wife rescuing her husband from a tyrant’s prison, mattered to him too deeply to abandon. The 1805 version, in three acts, was long and dramatically loose, its opening act spent on domestic intrigue while the rescue waited, and it opened in a Vienna under French occupation to a scattered audience. The 1806 revision, cut to two acts with his friend Stephan von Breuning, tightened the structure and then died in a quarrel with the management over receipts. The 1814 version succeeded because Georg Friedrich Treitschke rebuilt the libretto as a professional dramatist, reordering scenes, strengthening Florestan’s music and opening the ending outward, while Beethoven recomposed on a near-total scale. Fidelio is the catalogue’s record of a composer learning a genre by failing at it in public.

Q: What was Wellington’s Victory?

Wellington’s Victory, Opus 91, is a battle piece composed in 1813 to celebrate the Duke of Wellington’s defeat of the French at Vitoria. It was designed for the panharmonicon, a mechanical orchestra built by the inventor Johann Nepomuk Maelzel, and then scored for a real orchestra, in which form it was premiered in Vienna on 8 December 1813 at a benefit concert for wounded soldiers, sharing the programme with the first performance of the Seventh Symphony. Its first part depicts the battle, the English and French armies characterised by their national tunes and cannon and musket fire written into the percussion parts as structural events. Its second part is a victory symphony built on God Save the King, treated in full counterpoint. The piece was the greatest public success of Beethoven’s career, performed across Europe and outselling the symphonies, and it then became the subject of a bitter rights dispute between the composer and Maelzel.

Q: Did Beethoven’s commercial successes match his reputation?

No, and the mismatch is one of the catalogue’s most instructive facts. The works that earned were the works of access: Wellington’s Victory above all, the Septet, which for years was his most performed piece, the oratorio Christ on the Mount of Olives, a staple of British and American choral societies across the nineteenth century, and the sociable sonatas that sold in edition after edition. The works on which the modern reputation rests earned late, little or nothing in proportion: the Eroica was held back and argued over, the violin concerto failed and waited four decades for its audience, the late quartets were written to a prince’s commission at fifty ducats apiece and barely performed, and the Missa Solemnis was placed by subscription as a prestige manuscript rather than sold as a success. Beethoven’s income remained erratic at the height of his fame. His catalogue kept two sets of books, and they have never balanced.

Q: What is the Diabelli Variations based on?

The set is based on a short waltz by the Viennese publisher Anton Diabelli, issued in 1819 as the theme of a collective album: Diabelli invited the composers of Austria to contribute one variation each, and some fifty accepted, including Schubert and the child Liszt. Beethoven first declined, then took the theme up as an obsession, and across 1819 to 1823 he expanded his contribution into thirty-three variations, a structure so large that Diabelli published it separately in 1823 as Opus 120, a year before the collective album appeared. The waltz itself is sturdy, square and deliberately unremarkable, and the set’s drama is the distance travelled from it: the variations pass through parody, a funeral march, a nocturne, displays of learned counterpoint and a full fugue, before a closing minuet returns the theme transfigured. William Kinderman’s study of the work reads the sequence as a comedy of the creative process itself.

Q: Why are the late quartets considered difficult?

Their difficulty is a matter of procedure rather than obscurity. The late quartets abandon the contract the earlier works kept with a first-time listener: movements run together without pause, as in the seven-movement span of Opus 131; arguments unfold across forty minutes and demand that the listener hold an opening fugue in memory while its consequences are worked out; dense counterpoint replaces clear thematic signposts; and grief, parody and dance stand side by side without transitions to explain the joins. The demands on performers are of the same order, since the parts are individually exacting and the ensemble problems, of balance, intonation and shared breath, have to be solved before interpretation can begin. First audiences had no framework for any of this, and the works circulated in print as objects of study before they circulated as performances. Repeated hearings reorder the difficulty into logic, which is the usual experience of listeners who persist.

Q: Why was the Grosse Fuge replaced?

The replacement was a publisher’s proposal that the composer accepted on documented terms. At the premiere of the Quartet Opus 130 in March 1826 the audience applauded the work and encored two inner movements, but the fugal finale stood outside general comprehension, and the publisher Matthias Artaria judged the quartet unsellable with it in place. Through Karl Holz, the quartet’s second violinist and the composer’s associate, the proposal reached Beethoven: publish the fugue separately and supply a new finale. He agreed in the autumn of 1826, composed the replacement that November, the last music he completed, and prepared his own piano duet arrangement of the fugue to widen its market. The fugue appeared in May 1827 as Opus 133, dedicated to Archduke Rudolph. The motives were commercial and practical, and artistic in the form of a refusal: the movement was not withdrawn, it was promoted into independence.

Q: Should I start with the symphonies or the sonatas?

The answer depends on how you listen. If your habit is the concert hall, begin with the symphonies, which present the public Beethoven in his clearest form: the Seventh for rhythm, the Fifth for argument, the Eroica for scale, the Ninth when the others are familiar. If you play the piano, or if your listening is private and repeated, begin with the sonatas, which contain the whole career in one instrument’s literature, from the Pathétique through the Waldstein and Appassionata to the final trilogy of Opus 109 to 111, and which reward the kind of attention a desk gives better than a hall does. The two routes are not rivals. They converge on the same middle period from opposite sides, and the listening order proposed in this article alternates between them deliberately, because each teaches the ear something the other assumes.

Q: Is the Ninth Symphony a good entry point?

It is a qualified one. In its favour, the finale’s hymn is known to almost everyone before they meet the symphony, so the work arrives with a familiar door built into its last movement, and its sheer scale and sincerity have carried many first-time listeners straight through. Against it, the symphony runs well over an hour, its first movement is among the most demanding he wrote, and the finale’s great device, the parade of the earlier movements’ themes and their rejection in favour of the new one, only registers fully in a listener who knows what is being rejected and what the rejection costs. Heard after the Fifth and Seventh, the Ninth lands with its full weight. Heard entirely cold, it can impress without quite explaining itself. The practical verdict is to treat it as the summit of a short approach march rather than as the entrance, and to give it a whole evening when it comes.

Q: How do I work through the thirty-two piano sonatas?

Take them in groups rather than in a single chronological march, and let each group settle before moving on. Begin with the Pathétique and the two sonatas of Opus 27, including the one posterity calls Moonlight, which together show the early form at its most theatrical. Move to Opus 31 and then to the Waldstein and the Appassionata, the twin summits of the middle years, and pause there, since everything before them is preparation and everything after them is consequence. The shorter sonatas that follow, Opus 78, Opus 79, Les Adieux and Opus 90, form a deliberate valley worth taking slowly. Then climb in order: Opus 101, the Hammerklavier given its own week, and the final three, Opus 109, 110 and 111, heard as a trilogy in a single sitting at the end. The count of thirty-two includes the two slight sonatas of Opus 49 and the paired sonatas inside Opus 14 and 27, which is why casual references sometimes give a different total.

Q: How do I compare two recordings of the same symphony?

Fix your checkpoints in advance and hold them constant across both performances, because an unstructured comparison mostly measures recording quality and the mood of the listener. A workable set for a Beethoven symphony is the tempo of the opening bars and whether that tempo survives the movement’s later sections; whether the exposition repeat is taken, which alters the architecture by minutes; the pacing of the development’s climax; the handling of the join into the recapitulation; and the breadth of the finale’s coda. Listen to the same five-minute span in both recordings in immediate succession, then to a different span, and note the size and character of the orchestra where the information is available, since period instruments and a modern symphony orchestra are answering the question with different equipment. Keep brief notes against each checkpoint. After three or four comparisons the table you have built converts a preference into evidence, and the preference itself usually becomes clearer about its reasons.

Q: Which five Beethoven works give the best overview?

Five works can hold both bodies of the catalogue if they are chosen by function rather than by fame. Take the Seventh Symphony for the public art in its purest form, rhythm organising an entire structure without a programme or a text. Take the Appassionata for the middle-period piano, the instrument on which the career was built. Take the Violin Concerto for the serene public manner, the soloist floating above the argument. Take the Ninth Symphony for the public summit, the symphony that ends by addressing its audience directly through voices. And take the String Quartet Opus 131 for the private body at full stretch, seven movements in one span, written for almost nobody and now regarded by many players as the summit of the whole output. A defensible alternative five substitutes the Missa Solemnis for the Ninth or the Diabelli Variations for the concerto, and arguing the substitutions is itself an education in the catalogue.

Q: What should I listen for in the Missa Solemnis?

Begin with the architecture: the five sections of the mass ordinary carried at symphonic scale, each internally built like a movement. In the Gloria, listen for the closing fugue, where the rejoicing is organised into strict counterpoint. In the Credo, the centre of the work, listen for the hush that falls at the mystery of the incarnation and the sudden radiance of the resurrection, and for the way the whole vast structure pivots on those two moments. In the Sanctus, listen for the solo violin that enters in the Praeludium and descends through the texture as though from above the choir. In the Agnus Dei, listen for the prayer for peace and for the military music, distant trumpets and drums, that twice invades it from outside. Follow the text in translation on paper, allow the work an uninterrupted eighty minutes, and expect exhilaration and exhaustion to arrive together, as they were designed to.

Q: How did reception of Beethoven’s works change over time?

The profile of the fame inverted almost completely. In Beethoven’s lifetime the catalogue’s public face was the Septet, the battle piece Wellington’s Victory, the oratorio Christ on the Mount of Olives and the middle-period favourites, while the Missa Solemnis was a rumour among courts and the late quartets were effectively unperformed. Across the nineteenth century the symphonies and the piano sonatas were canonised in the concert halls of Paris and the German states, and Fidelio acquired the moral centrality of a national rescue opera. Across the twentieth the late works completed their rise to the summit of the reputation, the Grosse Fuge travelling from incomprehensible to prophetic, while the battle piece and the occasional works fell into apology and footnote. The Ninth Symphony left the concert hall altogether and became an institution, adopted as the anthem of Europe. Reception history therefore warns against any timeless ranking: reputations attach to bodies of work in succession, and each generation finds the Beethoven it has learned to hear.
