Cage’s innovations with sound, instrumentation, performance, and composition all helped redefine music in the 20^th century. More specifically, his use of chance and the creative ways in which he utilized performers in his works helped inform and shape avant-garde movements like Neo-Dada, Fluxus, and Conceptual art. His innovations also had a profound influence on late-20^th-century developments in sound art and performance art, which focused increasingly on context and variability. Through his collaborations at Black Mountain College, Cage also encouraged artists such as Rauschenberg to explore visual art that incorporated chance, an element that would have a major impact on the course of modern art during the second half of the century.
