Henry_Cowell

Henry Dixon Cowell (; March 11, 1897 – December 10, 1965) was an American composer, writer, pianist, publisher, teacher and the husband of Sidney Robertson Cowell. Earning a reputation as an extremely controversial performer and eccentric composer, Cowell became a leading figure of American avant-garde music for the first half of the 20th century — his writings and music serving as a great influence to similar artists at the time, including Lou Harrison, George Antheil, and John Cage, among others. He is considered one of America's most important and influential composers.Cowell was mostly self-taught and developed a unique musical language, often blending folk melodies, dissonant counterpoint, unconventional orchestration, and themes of Irish paganism. He was an early proponent and innovator of many modernist compositional techniques and sensibilities, many for the piano, including the string piano, prepared piano, tone clusters, and graphic notation.
