36 Fugues

36 Fugues, sometimes assigned opus number 36, is a cycle of fugues for piano composed by Anton Reicha. It was first published by the composer in 1803 and served as an illustration of a nouveau système Reicha invented for fugue composition. This system involved, among other things, extensive use of polyrhythms, derived from traditional music, and fugal answers on any and all scale degrees, rather than just the dominant, which was standard at the time.
