In A minor, in one-part form.

• A [a (measures 1-8) + b (measures 9-16)]
• A [a (measures 17-24) + b (measures 25-32)]
• A1 [a (measures 33-40) + Coda (measures 41-48)]

Although the piece is broadly divided into three sections, it is essentially a repetition of section A. Therefore, it is considered a one-part form, with section A being the only substantial section.

In contrast to section 'a', which features clear exposition and a sense of conclusion, section 'b' repeats short phrases in the left hand while progressing towards a half cadence. These two sections together constitute the large section A.
