Frédéric Chopin's Nocturne in E-flat Major, Op. 9 No. 2 (published 1833) is one of the most celebrated pieces in the solo piano repertoire, known for its singing, ornamented melody over a gently rocking left-hand accompaniment. Influenced by the Irish composer John Field who invented the nocturne form, Chopin elevated the genre to new expressive heights.
