It is in A major and in binary form.

A [a (measures 1-8) + a (measures 9-16)]

B [b (measures 17-24) + a1 (measures 25-33)]

The buoyant motif from the opening two measures serves as the central axis for the entire development. In section A, the tonic pedal point is dominant, which, despite the wide range of the melodic line, creates a graceful and tranquil impression. In subsection b, there is a "cantabile" indication, but here, one should add a singing nuance, mindful of the descending bass line and the horizontal flow.
