In C major, in ternary form.

• A [a (measures 1-4) + b (measures 5-8)]
• B [c (measures 9-12) + c1 (measures 13-16) + transition (measures 17-20)]
• A1 [a (measures 21-24) + a (measures 25-28)]

The piece begins with the left hand, followed by the melody in the right hand. This is reminiscent of Bach's Invention No. 1. Section b, starting from measure 5, modulates to A minor and, like the beginning of section a, starts with the left hand but descends instead of ascending. A polyphonic texture is evident throughout. The middle section B features numerous parallel and sequential progressions, contrasting with A. It modulates to E major. A is recapitulated after a transitional passage from measures 17-20.
