The main key is E minor. It is in binary form with an introduction and a coda.

• Introduction (measures 1-6)
• Main Section [a (measures 7-14) + b (measures 15-26)]
• Coda (measures 27-30)

The introduction and coda are composed of a repetitive motif of sixteenth notes; however, contrary to the busy image suggested by the short note values, the melodic line possesses a gentle, narrative quality, reminiscent of the beginning and end of a folk tale.

In section b, the music modulates to the parallel key of G major. The descent of the leading tone F# in measure 18, instead of its typical upward resolution, strongly evokes a folk element. While the phrase length in the main section is primarily based on 8 measures, section b, due to its modulation to G major, first cadences in G major at the 8th measure of the phrase. It then concludes definitively in the main key of E minor after a subsequent 4-measure extension.
