"The Nocturnes, Op. 9 are a set of three nocturnes written by Frédéric Chopin between 1830 and 1832 and dedicated to Madame Camille Pleyel. The work was published in 1833."
"Chopin composed his popular Nocturne in E flat major, Op. 9, No. 2 when he was about twenty. Like much of Chopin's music, this nocturne is tinged with melancholy."
