This is a list of compositions by Frédéric Chopin by genre. There is a separate list by opus number. Most of Chopin's compositions were for solo piano, though he did compose two piano concertos as well as some other music for ensembles. His larger scale works such as sonatas, the four scherzi, the four ballades, the Fantaisie in F minor, Op. 49, and the Barcarolle in F major, Op. 60 have cemented a solid place within the piano repertoire, as have his shorter works: the polonaises, mazurkas, waltzes, impromptus and nocturnes. Two important collections are the Études, Op. 10 and 25 (which are a staple of that genre for pianists), and the 24 Preludes, Op. 28 (a cycle of short pieces paired in a major key/relative minor key pattern following the circle of fifths in clockwise steps). Also, Chopin wrote numerous song settings of Polish texts, and chamber pieces including a piano trio and a cello sonata. This listing uses the traditional opus numbers where they apply; other works are identified by numbers from the catalogues of Maurice J. E. Brown (B), Krystyna Kobylańska (KK), Józef Michał Chomiński (A, C, D, E, P, S), and Jan Ekier (WN, Dbop.).
