- Andante -

Like a nocturne

Music structure: introduction, A, B, coda.

Introduction: four measures, calmly decomposing chords, preparing to introduce the main melody. This accompaniment makes people feel like they are on a tranquil lake.

A: aba three-part form plus coda

a: It consists of two eight-bar musical phrases. The first half of the sentence is four bars, and then the second half of the sentence is the same. It forms a big phrase of eight measures, and then repeats it to form a section of sixteen measures. Of course, Chopin's repetitions always add decoration and changes to the melody.

b: This is a paragraph that is compared with paragraph a, but the contrast is not obvious at first.

Reappearance a: Same as the previous a, but with a counterpoint melody added in the next eight bars.

Small coda: The accompaniment pattern has not changed, and the melody is composed of sixteenth notes.
