Nocturnes, Op. 9 (Chopin)

9 are a set of three nocturnes for solo piano written by Frédéric Chopin between 1831 and 1832, published in 1832, and dedicated to Madame Marie Pleyel.

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 128 meter, having a similar structure to a waltz.

The nocturne opens with a legato melody, mostly played piano (quietly), containing graceful upward leaps which becomes increasingly wide as the line unfolds.

A sonorous foundation for the melodic line is provided by the widely spaced notes in the accompaniment, connected by the damper pedal.

The second contrasting section, Agitato in B minor, is a very dramatic one with a combined melody and counter-melody in the right hand and continuous eighth note arpeggios in the left, which requires an amount of virtuosity.

The piece is full of coloratura ornaments, and it ends in a small cadenza similar to Opus 9 no.
