Explanation:
John Cage, an American musician, artist, and philosopher, was one of the earliest proponent of post-war Avant-garde. Cage is regarded as the most influential composers of the 20th century for his music philosophy and an emphasis on one's life.
Cage described music as "a purposeless play" in his Experimental Music lecture of 1957. His theory was highly inspired by Indian philosophy and Zen Buddhism and his extensive research of South Asian cultures.
He believed that music does not attempt to bring order out of chaos nor to suggest improvements in creation, but simply a way of waking up to the very life we're living.
