Chopin, Piano Nocturne In B-flat Minor, Op. 9, No. 1 1:05 Stock Image

Frédéric Chopin`s Nocturne in B-flat minor, Op. 9, No. 1 has a rhythmic freedom that came to characterize Chopin`s later work. The left hand has an unbroken sequence of simple arpeggios throughout the entire piece, while the right hand moves with freedom in patterns of seven, eleven, twenty, and twenty-two notes. The opening section moves into a contrasting middle section, 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 and the nocturne concludes peacefully with a Picardy third.
