The piece is in ternary form.

• A [a (measures 1-8) + b (measures 9-16)]
• B [c (measures 17-24) + d (measures 25-32)]

※This is an A B A ternary form, returning to A via Da Capo and concluding at measure 16.

The main key is A minor. While there is a brief modulation to C major in the middle section (measures 17-20), the rest of the piece is constructed entirely in the main key, contributing to an overall melancholic atmosphere in the minor mode. Measures 9-12 are better understood not as a modulation to D minor, but rather as a borrowing of the dominant seventh chord from the subdominant key (IV) in measure 10. The piece concludes at measures 15-16, where the left hand executes a plagal cadence (I-IV-I).
