Carl Ruggles

Carl Ruggles (born Charles Sprague Ruggles; March 11, 1876 – October 24, 1971) was an American composer, painter and teacher. His pieces employed "dissonant counterpoint", a term coined by fellow composer and musicologist Charles Seeger to describe Ruggles' music. His method of atonal counterpoint was based on a non-serial technique of avoiding repeating a pitch class until a generally fixed number of eight pitch classes intervened. He is considered a founder of the ultramodernist movement of American composers that included Henry Cowell and Ruth Crawford Seeger, among others. He had no formal musical education, yet was an extreme perfectionist — writing music at a painstakingly slow rate and leaving behind a very small output.

Famous for his prickly personality, Ruggles was nonetheless close friends with Cowell, Seeger, Edgard Varèse, Charles Ives, and the painter Thomas Hart Benton. His students include the experimental composers James Tenney and Merton Brown. Conductor Michael Tilson Thomas has championed Ruggles' music, recording the complete works with the Buffalo Philharmonic and occasionally performing ''Sun-Treader'' with the San Francisco Symphony. Especially later in life, Ruggles was also a prolific painter, selling hundreds of paintings during his lifetime. Provided by Wikipedia
