Grande sonate 'Les quatre âges'

20 ans

The sonata opens with 20 ans, a quickly played piece based in D major but also with many passages in the relative minor key of B minor. The young man's 'clumsiness' is marked for example by sudden 'wrong chords' – one in B-flat major is marked 'ridente' (Italian: laughing). The key, tempo and ternary form of this movement are similar to Frédéric Chopin's Scherzo No. 1 (Op. 20). The sonata thus marks itself from the start as different from any previous sonatas, by beginning effectively with a scherzo. The movement, albeit opens in D major, later changes into B minor after a slow, melodic section in B major, and ends with a B major flourish.

30 ans: Quasi-Faust

The second movement, in D-sharp minor (i.e. a key a semitone above the first movement) and ending in the relative major key of F-sharp major, called 30 ans and subtitled "Quasi-Faust", is the most substantial piece in the sonata, in a very extended sonata form. Ronald Smith comments on the first subject of this movement:

The duality of this subject, like the dual nature of man, anticipates by six years a similar duality in the Liszt Sonata in which threatening repeated notes are also a feature of the answering phrase.

However, Smith also points out that whilst Liszt treats his material rhapsodically, Alkan keeps to the classical form, if not proportions.

The movement contains much of the most difficult parts in the entire sonata like extremely rapid chords and octaves, huge leaps in both hands and other passage works. Amid the movement, there is a brief, eight-voice fugue.

Raymond Lewenthal wrote regarding this movement: "[it] is actually a tone poem within a tone poem ... it forms the apex of the sonata and it is the longest and most difficult movement. It stands very well by itself and no one performing it without the other movements need fear being criticised for serving up a bleeding chunk."

40 ans: Un heureux ménage

40 ans, titled "Un heureux ménage" (A Happy Household), illustrates family life for the aging man, with sections that represent "the children" and "a prayer". The movement is in the 'simple' key of G major.

50 ans: Prométhée enchaîné

The sonata ends with 50 ans, called "Prométhée enchaîné" (Prometheus Bound), which gravely depicts the man looking toward death. This movement, in G-sharp minor, has the same tonal relationship to the third movement as the second has to the first. Contrary to classical traditions, however, the key in which the sonata ends is very distant from that in which it begins.

Relationship to the Liszt Sonata

The originality of this work, together with some structural similarities such as those referred to above, have led writers such as Ronald Smith, Kenneth Hamilton and Jack Gibbons to surmise that Liszt may have known this work before writing his own Sonata in B minor. However, there is no evidence that Liszt (or Alkan himself, for that matter) ever played the 'Grande sonate' in public or private, although the two pianists certainly knew each other in Paris and were aware of each other's work. However, the publication of the 'Grande sonate' was unfortunate in its timing; in early 1848 the revolution emptied the capital of musical life, and Alkan's failure to obtain a professorship at the Paris Conservatoire later in the year led to his withdrawal from the concert scene. Liszt also left Paris for Weimar. For these reasons, consideration of Alkan's influence on Liszt's Sonata must remain speculative.

In popular culture

The sonata plays a part in the plot of The Forgotten Room, a novel by Lincoln Child.
