Aleatoric music, also known as aleatory music, is music with a random element. Chance elements within a piece can be used for composition, as well as for live performance. When a piece is being composed, random elements can be used to influence the outcome of a final musical piece.
From Wikipedia, the free encyclopedia. Incidental music is music in a play, television program, radio program, video game, film, or some other presentation form that is not primarily musical. The term is less frequently applied to film music, with such music being referred to instead as the film score or soundtrack.
