Finale: Presto (C minor): A virtuosic finale in C minor and sonata-rondo form. The most difficult and most effective movement of the sonata, it, among the finales of Chopin's piano sonatas, takes the longest to perform.

Larghetto (A♭ major): This piece is set in 5/4 time, which is very unusual for pieces of that era. The third beat of each five-beat bar carries a secondary accent, which is marked explicitly in certain bars. In other places, it can be inferred, and in still other places Chopin seems to defy this convention and not expect this. James Huneker, in his introduction to the 1895 American publication of the Mikuli edition of the work, calls this unusual characteristic a "failed novelty."

Menuetto (E♭ major):
A minuet (/ˌmɪnjuˈɛt/; also spelled menuet) is a social dance of French origin for two people, usually written in 3/4 time but always played as if in 6/8 (compound duple metre) to reflect the step pattern of the dance. The English word was adapted from the Italian minuetto and the French menuet. ...

In the aspect of key relations does this movement break from tradition - the second group of themes is based in C minor as much as is the first, so that the dramatic contrast of key which Cedric Thorpe-Davie among others identify as the heart of sonata form is lost. Furthermore, the recapitulation begins in the remote key of B♭ minor, with the second theme appearing in G minor.

Allegro maestoso (C minor) : The first movement is in sonata form. The sonata form (also sonata-allegro form or first movement form) is a musical structure generally consisting of three main sections: an exposition, a development, and a recapitulation. While it is typically used in the first movement of multi-movement pieces, it is sometimes used in subsequent movements as well—particularly the final movement.
The standard definition focuses on the thematic and harmonic organization of tonal materials that are presented in an exposition, elaborated and contrasted in a development and then resolved harmonically and thematically in a recapitulation. In addition, the standard definition recognizes that an introduction and a coda may be present. Each of the sections is often further divided or characterized by the particular means by which it accomplishes its function in the form.

The second episode is made up of numerous imitations and pedals in each voice, continuously developing throughout.

The re-exposition is composed of subject-answer between measures 46 and 52, along with a pedal in voice 3.
