The Nocturnes, Op. 9 are a set of three nocturnes written by Frédéric Chopin between 1830 and 1832, published that year, and dedicated to Madame Marie Pleyel. The second nocturne of the work is regarded as Chopin's most famous piece.
Nocturne in B-flat minor, Op. 9, No. 1
This nocturne has a rhythmic freedom that came to characterize Chopin's later work. The left hand has an unbroken sequence of eighth notes in simple arpeggios throughout the entire piece, while the right hand moves with freedom, occasionally in patterns of seven, eleven, twenty, and twenty-two in the form of polyrhythms. The piece is 85 measures long and in 6/4 meter. It is written in ternary form; after the primary theme, the secondary theme starts in measure 19, followed by a modified version of the primary theme in measure 70.
The opening section moves into a contrasting middle section in the same key signature, which flows back to the opening material in a transitional passage where the melody floats above seventeen consecutive bars of D-flat major chords. The reprise of the first section grows out of this, followed by a Picardy third ending.
Nocturne in E-flat major, Op. 9, No. 2
Chopin composed his best-known Nocturne in E-flat 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). Nocturne in E-flat major 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, 12 beats to the measure subdivided into four groups of 3 beats each.

Nocturne in B major, Op. 9, No. 3
It is in ternary form A-B-A. The first section is marked allegretto. The main theme is chromatic, but filled with nostalgic energy. 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 8th note arpeggios in the left, which requires an amount of virtuosity. The piece is full of coloratura ornaments, and ends with a wide chord in the left hand accompanied with right hand triplets in a high octave to lead to a legatissimo smorzando adagio (senza tempo).[further explanation needed]
