The Studies for Player Piano is a series of 49 études for player piano by American composer Conlon Nancarrow. Often exploring complex rhythmic variations beyond the ability of a human pianist, these compositions are some of the best-known and celebrated compositions by Nancarrow, even though they are generally not considered a set of compositions, but rather individual compositions that were given the same title and status. The dates of composition are unknown, but approximate ranges have been given according to best evidence.
