in E♭ major, Op. 9, No. 2 when he was around twenty years old. This well-known nocturne is in rounded binary form (A, A, B, A, B, A) with coda, C. It is 34 measures long and written in 12 8 meter, having a similar structure to a waltz.
The A and B sections become increasingly ornamented with each recurrence. The penultimate bar utilizes considerable rhythmic freedom, indicated by the instruction, senza tempo (without tempo). The nocturne opens with a legato melody, mostly played piano (quietly), containing graceful upward leaps which becomes increasingly wide as the line unfolds. This melody is heard again three times during the piece. With each repetition, it is varied by ever more elaborate decorative tones and trills. The nocturne also includes a subordinate melody, which is played with rubato.
A sonorous foundation for the melodic line is provided by the widely spaced notes in the accompaniment, connected by the damper pedal. The waltz-like accompaniment gently emphasizes the 12/8 meter.
