Early in his career, his music received little attention, and many of his compositions went years without being performed. Through the efforts of contemporary musicians like Henry Cowell and Lou Harrison, his music's quality was later recognised by the general public, and he was dubbed a "American original." He was also one of the pioneers of systematic experimental music composition, using a variety of musical techniques such as polytonality, polyrhythm, tone clusters, aleatory elements, and quarter tones.
