The Nocturnes, Op. 15 are a set of three nocturnes for solo piano written by Frédéric Chopin between 1830 and 1833. The work was published in January 1834, and was dedicated to Ferdinand Hiller.[1] These nocturnes display a more personal approach to the nocturne form than that of the earlier Opus 9. The melodies and emotional depth of these nocturnes have thus been thought of as more "Chopinesque."[2]
