Over 230 Chopin works survive; some compositions from early childhood have been lost. All his known works involved the piano. Only a few ranged beyond solo-piano music, as either piano concertos or chamber music.

Chopin composed:

• 59 mazurkas

• 27 études (twelve in the Op. 10 cycle, twelve in the Op. 25 cycle, and three in a collection without an opus number)

• 27 preludes

• 21 nocturnes

• 20 waltzes

• 18 polonaises, including one with orchestral accompaniment and one for cello and piano accompaniment

• 5 rondos

• 4 ballades

• 4 impromptus

• 4 scherzi

• 4 sets of variations, including Souvenir de Paganini

• 3 écossaises

• 3 piano sonatas

• 2 concerti for piano and orchestra, Op. 11 and 21

He also composed: a fantaisie, an Allegro de concert (which is possibly the remnant of an incomplete concerto), a barcarole, a berceuse, a bolero, a tarantelle, a contredanse, a fugue, a cantabile, a lento, a Funeral march, and a Feuille d’album.

Chopin’s other works include: a krakowiak for piano and orchestra; Variations on “Là ci darem la mano” for piano and orchestra; fantasia on themes from Polish songs with accompanying orchestra; a trio for violin, cello and piano; a sonata for cello and piano; a Grand Duo in E major for cello and piano on themes from Giacomo Meyerbeer’s opera Robert le diable, co-written with Auguste Franchomme; and 19 Polish songs for voice and piano.
