Frédéric Chopin - Nocturne in F sharp Major, Op. 15, No. 2

Composed in 1832, it is a technically challenging piece in A-B-A form, in 2/4. The first section, Larghetto (mm.40), features an intricate, elaborately ornamental melody over an even quaver bass. The second section, labelled doppio movimento (double speed), resembles a scherzo with dotted quaver-semi quaver melody, semiquavers in a lower voice in the right hand, and large jumps in the bass. The final section is a shortened version of the first (14 bars rather than 24) with characteristic cadenzas and elaboration, finishing with an arpeggio on F♯ major, falling at first, then dying away.
