Frédéric Chopin's output mostly consists of pieces for solo piano. There are also six works for piano and orchestra (two of which are piano concertos), and a small amount of chamber music. Some of his standalone works are well-known, such as the Barcarolle in F major, the Fantaisie in F minor, the Berceuse in D major, and some of the 19 Polish songs. Most of the other lesser-known works were published only after his death, contrary to his express wishes that all his unpublished manuscripts should be burned.
While sometimes disregarded in the concert repertoire (particularly the posthumously published works), most of these miscellaneous works have been recorded, in some cases numerous times.
Posthumous opus numbers and other catalogue designations Chopin expressed a death-bed wish that all his unpublished manuscripts be destroyed. However, at the request of the composer's mother and sisters, Julian Fontana selected 23 unpublished piano pieces and grouped them into eight posthumous opus numbers (Opp. 66–73). These works were published in 1855, and include in order: Fantaisie-Impromptu, 4 mazurkas, 4 mazurkas, 2 waltzes, 3 waltzes, 3 polonaises, a nocturne, a Marche funèbre, 3 écossaises, and a rondo. In 1857, 17 of Chopin's Polish songs were published as Op. 74.
Various other works have been subsequently published, but have not been given opus numbers. They are identified by alternative numbers from the catalogues of: Maurice J. E. Brown (B), Krystyna Kobylańska (KK), and Józef Michał Chomiński (A, C, D, E, P, S).
