Edgard Victor Achille Charles Varèse (French: [ɛdɡaːʁ viktɔːʁ aʃil ʃaʁl vaʁɛːz]; also spelled Edgar Varèse; December 22, 1883 – November 6, 1965) was a French-born composer who spent the greater part of his career in the United States. Varèse's music emphasizes timbre and rhythm and he coined the term "organized sound" in reference to his own musical aesthetic. Varèse's conception of music reflected his vision of "sound as living matter" and of "musical space as open rather than bounded".
