녹턴, Op. 27 (Nocturnes, op. 27)

The Nocturnes, Op. 27 are a set of two nocturnes for solo piano composed by Frédéric Chopin. The pieces were composed in 1836 and published in 1837. Both nocturnes in this opus are dedicated to Countess d'Appony. This publication marked the transition from triplets of nocturnes to contrasting pairs. Whereas the Nocturnes, Op. 9 and Op. 15 included three nocturnes each, the remainder of Chopin's nocturnes published during his lifetime were in sets of two. David Dubal feels that the pieces are "more aptly described as ballades in miniature". Blair Johnson states that these two nocturnes are "two of the most powerful—and famous—nocturnes [Chopin] has ever penned" and that these nocturnes are "virtually unrecognizable" to the nocturne tradition of John Field.
