Generative Music concerns works that are totally process based. Generative works generally do not involve exact repetition and, when not resulting in a fixed composition, tend not to be identical between performances. This term is both used in conjunction with early process pieces by members of the school of minimalism (e.g., Steve Reich) and those involved with relevant digital algorithmic works.
