A '''heterophonic''' musical texture is one in which one or more instruments play (or one or more voices sing) a variation on the main melody simultaneously. Usually, this occurs while one instrument plays the melody unadorned. Heterophony is a defining characteristic of much of the world's music, including most traditional East Asian music (notably in Japanese [[Gagaku|''Gagaku'']]), which did not have harmony or [[polyphony]] before contact with Western music. It was also a characteristic of one tradition of [[Hymn|Hymnody]] in the 17th and 18th centuries, a tradition called "lining out" in which a song leader would sing a line of a hymn, and the congregation would answer, every member singing in the speed or style of their choice. Most notably, this style was adopted in early [[New Orleans]] [[jazz]].
