Allegro vivace, A minor, 3/8 time.

It adopts a cyclical form of A-B-C-A’-B’-C’-A’’-Coda, with each section separated by a general pause. First, the opening theme (A) is presented in A minor by a unison scale. This theme is always played fragmentarily, suspended by a half cadence. Following this, a new, more active theme (B) appears in A major (m. 31), and from m. 59, a new theme (C) is presented dolce. This Theme C begins in D major, but after an intervening section in E major, Theme C reappears, remaining in E major. From m. 164, the previously presented material is recapitulated in different keys. The opening theme is in E minor, Theme B is in E major, and Theme C begins in G major before modulating to A major. Following this, when the opening theme returns in a shortened form in the tonic key of A minor (m. 310), a coda full of dynamic contrasts appears, concluding the piece in A major.
