曲谱简介：

This popular nocturne is in rounded binary form (A, A, B, A, B, A) with coda, C. 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). Nocturne in E-flat major opens with a legato melody, mostly played piano, 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.
