Frédéric Chopin's waltzes are pieces of moderate length for piano, all written between 1824 and 1849. They are all in waltz triple meter, specifically 3/4 (except Op. P1/13, which is in 3/8 time), but differ from earlier Viennese waltzes in not being intended for dancing. Some are accessible by pianists of modest capability, others require advanced technique. Chopin may have written as many as 37 piano waltzes, but only nineteen (along with one inauthentic waltz) are numbered and only eight were published (in Opp. 18, 34, 42 and 64) before he died. His desire was that any unpublished works should be burned, but his sister Ludwika and Julian Fontana proceeded anyway to publish Waltzes 9–13 (as Opp. 69 and 70). Six waltzes composed 1826–1831 and present in Frédéric’s Paris home were at first preserved but then lost in an unintended 1863 fire in Ludwika's house. Another six were eventually published as Waltzes 14–19. These Chopin had given to related people without guarding the manuscripts. Waltz 18 was untitled; it is in 3/4 time and bears some characteristics of a waltz but is marked Sostenuto. Waltz 17 is not accepted as authentic by the Fryderyk Chopin Institute; to the other five in this group it has assigned WN numbers (29, 18, 28, 53 and 63). Waltz 20 is likewise inauthentic. Another authentic waltz in A minor was rediscovered in 2024 and has not yet been published or numbered. Separately, the last variation of Chopin’s (authentic) Variations on a German National Air (Der Schweizerbub), WN 6, is in the form of a waltz. Besides, there remain: Famous are the Minute Waltz and the Waltz in C♯ Minor, both from Op. 64, the last set of waltzes Chopin published before his death.
