Analysis

The main key is E-flat major, and the piece is interpreted as a binary form with a coda.

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

A1 [a (measures 17-24) + b1 (measures 25-32)]

Coda [measures 33-42]

Although sections A and A1 are almost identical, their structural relationship resembles that of the exposition and recapitulation in sonata form. In the first half, Section A modulates to the dominant key, while in the latter half, Section A1's b section develops in the tonic key. Based on this, the relationship between exposition and conclusion was determined, leading to its interpretation as a binary form. Incidentally, if the same section were merely repeated, it would be considered a one-part form.

The theme is a melody that frequently uses appoggiaturas; while smooth, it is characterized by a contour that is difficult to grasp. In the b section, it reaches the dominant key via a sequence. Subsequently, from measure 17, the theme is recapitulated in the tonic key, and in measure 25, the b section develops in the tonic key. From measure 33, a long four-measure phrase appears with a melodic line containing descending passing tones, which is then repeated an octave lower from measure 37, leading to the conclusion.
