The genesis of the work reaches back to 1819 when the Viennese music publisher Anton Diabelli circulated a waltz of his own invention to fifty composers, each of whom was requested to contribute a variation to a collective endeavour. The project was designed to generate publicity for Diabelli’s firm. The collaborative volume, with variations from Carl Czerny, Franz Schubert, and the young Franz Liszt among many others, was published independently from Beethoven’s gigantic set. Despite Beethoven having expressed an initial distaste for it, the theme nevertheless triggered a creative brainstorm. Before long he had conceived not one, but twenty-three variations, ten fewer than the final number. The study of Beethoven’s manuscripts from 1819 has cast new light on the structure and import of the piece. After having set it aside for several years, he expanded his draft from within in 1823, adding variations 1, 2, 15, 23 to 26, 28, 29 and 31 to the pre-established order, while greatly elaborating the conclusion.

During the process of composition, Beethoven often de-emphasized or obliterated the most obvious similarities between the variations in his sketches, while imparting to each finished variation a sharply defined individuality of character. The waltz is treated as a reservoir of unrealized possibilities out of which the variations generate an almost encyclopaedic range of contexts. The psychological complexity of the ‘Diabelli’ Variations arises above all from this tension between the commonplace theme as point of departure and the seemingly unlimited horizon of the variations. The range of pulse, movement, texture and sonority explored here is so prodigious as to fully justify von Bülow’s description of Op 120 as ‘a microcosm of Beethoven’s art’.

No other piece by Beethoven is so rich in allusion, humour and parody. Trivial or repetitious features of the waltz, such as the C major chords repeated tenfold with a crescendo in the right hand in the opening bars, can be mercilessly exaggerated as in Variation 21, or dissolved into silence as in Variation 13. Inconspicuous elements of the theme, such as the ornamental turn heard at the outset, can assume astonishing importance, as in Variations 9, 11 and 12 which are based throughout on this turn. Several variations allude to Mozart, Bach and other composers. The most obvious of these is the reference, in the unison octaves of Variation 22, to ‘Notte e giorno faticar’ from the beginning of Mozart’s Don Giovanni. This allusion is brilliant not only through the musical affinity of the themes – which share, for example, the same descending fourth and fifth – but through the reference to Mozart’s Leporello. Beethoven’s relationship to his theme, like Leporello’s to his master, is critical but faithful, inasmuch as he thoroughly exploits its motivic components. And like Leporello, the variations after this point gain the capacity for disguise. Variation 23 is an étude-like parody of pianistic virtuosity alluding to the Pianoforte-Method by J B Cramer, whereas Variation 24, the Fughetta, shows an affinity in its intensely sublimated atmosphere to some organ pieces from the third part of the Clavierübung by Bach.

The work as a whole consists of one large form with three distinct regions. The opening variations generally remain close to the basic attributes of the theme (such as its metre) but show gradually increasing freedom, which at last turns into dissociation with Beethoven’s juxtaposition of two contrasting canonic variations (Nos 19 and 20), whereas in No 21 the structural parts of each variation half are themselves placed into opposition. In the opening bars of Variation 21, a grotesque exaggeration of the turns and repeated chords from the waltz annihilates the inward stillness of Variation 20; this most shocking contrast is placed at the temporal mid-point of the entire cycle. The Janus face of No 21 marks the extreme limit of the progression toward dissociation that had begun about ten variations before.

A sense of larger formal coherence is created in part through unusually direct reference to the melodic shape of the original waltz in its original register in three of the variations inserted in 1823 – Nos 1, 15 and 25. Variation 1 is an impressive but somewhat stilted march in which the bass initially spells out the descending fourth from the waltz, creating accented clashes with the treble; Variation 15 is a miniature (the shortest of all thirty-three variations) with a static and peculiar harmonic plan, and its capricious two-octave skip in the bass in the second half has provoked ‘correction’ from puzzled editors. By parodying the theme directly in these variations, with its melodic contours intact, Beethoven made the waltz itself into an indispensable foundation for the overall musical progression. And if the elusive caricature embodied in Variation 15 calls forth the theme again as a kind of hallucination at the very moment when drastic, bewildering contrasts have gained the upper hand, this allusion to the outset of the work is broadened in the following pair of march variations, Nos 16 and 17, which are counterpoised to Variation 1 (the march more stilted in character).

In Variation 25 the waltz is reincarnated as a humorous German dance, but this image is gradually obliterated in the interconnected series of fast variations culminating in No 28, in which harsh dissonances dominate every strong beat throughout. This series of variations also marks the beginning of a consolidation in the form of the whole.

The process of rhythmic intensification from No 25 to No 28 offers special challenges to performers. Beethoven spreads the sixteenth-note motion drawn from the bass of the waltz parody (No 25) over all the pitch registers in the ensuing variation (No 26). The legato phrasing embraces paired groups of three sixteenths each, suggesting a metre of 6/16, but Beethoven retains the 3/8 metre (as well as the basic tempo) of No 25. The rhythmic impulses of the triple metre thus fall on the second and fourth sixteenths of each group of six notes, with the phrasing extended over the bar-lines throughout. This shifting pattern of metrical impulses imparts dynamic tension to the figuration, enhancing the upbeat character of the first half of each phrase. Then, in No 27, Diabelli’s ‘cobbler’s patch’ sequences of a rising semitone and a third become the basis for the figuration in rhythmic diminution, expressed in rapid triplet sixteenth-notes. Diabelli’s motif is written in steady quarter-notes, but Beethoven compresses his motivic variant so radically that it appears no fewer than twenty-four times in the opening eight bars of the variation! The dissonant semitone relation derived from the theme infuses the music with an intense energy, generating a frenzied chain of imitative motivic entries driving into the highest register in the second half of the variation. This climactic passage is Beethoven’s ultimate parody of the ‘cobbler’s patch’ sequences from the waltz.

Variation 28 then carries Beethoven’s rhythmic development to yet another stage, as the process of foreshortening motivates a compression of the metre to shorter bars of 2/4 time, while reducing the basic content of the music to the dissonant semitone – now expressed in the multiple contrapuntal voices embodied in the accented diminished-seventh and augmented-sixth chords.

After Variation 28 we enter a transfigured realm in which Diabelli’s waltz and the world it represents seem to be left behind. A group of three slow variations in the minor culminates in Variation 31, an elaborate aria reminiscent of the decorated minor variation of Bach’s ‘Goldberg’ set, but also foreshadowing the style of Chopin. The energetic fugue in E flat that follows is initially Handelian in character; its second part builds to a tremendous climax with three subjects combined simultaneously before the fugue dissipates into a powerful dissonant chord. An impressive transition leads to C major and to the final and most subtle variation of all: a Mozartian minuet whose elaboration through rhythmic means leads, in the coda, to an ethereal texture unmistakably reminiscent of the fourth variation of the Arietta movement from Beethoven’s own last sonata, Op 111, composed in 1822. The many parallels between Op 111 and the final Diabelli variation are structural in nature and extend to thematic proportions and the use of an analogous series of rhythmic diminutions leading, in each case, to the suspended, ethereal texture; but the most obvious similarity surfaces in the concluding passages outlining the descending fourth C–G, so crucial in both works.

Herein lies the final surprise: the Arietta movement, itself influenced by the Diabelli project, became in turn Beethoven’s model for the last of the ‘Diabelli’ Variations. The end of the series of allusions thus became a self-reference, a final point of orientation within a work of art whose vast scope ranges from ironic caricature to sublime transformation of the commonplace waltz.
