Allegro, E-flat major, 6/8 time

A bright final movement written in sonata form. The first theme group of the exposition is in E-flat major, consisting of a light, soft section (mm. 1-14) and a dynamic, loud section with sixteenth-note accompaniment (mm. 14-20). When the first theme group reaches a half cadence, the second theme group is presented from measure 21 in the dominant key of B-flat major. Here, the same melody is played twice, accompanied by eighth notes and sixteenth notes. Interspersed with a sudden modulation to D-flat major (m. 37), the exposition closes in B-flat major.

The development section opens in F minor, with this B-flat serving as the seventh of the dominant seventh chord. It consists of a first half supported by sixteenth-note accompaniment and a second half primarily featuring eighth notes; both sections undergo rapid modulations due to the frequent use of sequences.

In the recapitulation (m. 86), both theme groups from the exposition return in the tonic key. Just as the second theme group in B-flat major deviated to D-flat major in the exposition, so too in the recapitulation, at the same point in the second theme group, it deviates from E-flat major to G-flat major. The technique observed here, of shifting to a mediant key in both the exposition and the recapitulation, can be interpreted as an embryonic form of Schubert's later sonata forms, which present three themes in three keys.
