A great composer representing modern America. He made a strong impact on traditional Western music with his concept of "chance music," a non-Western form of musical philosophy and expression, which he established as one of the main styles of contemporary music. He has been a strong motive force in the most progressive group of modern composers as a pioneer of such revolutionary movements and has widely influenced not only musicians but also artists in other fields, such as dancers, poets, painters, sculptors, and photographers.
