William Copper is an American composer of contemporary classical music, a theorist, and the world’s authority on Intonalism, the science of structuring music according to intonation. His music is praised for its beauty, structural integrity, and innovative originality. He has been a life-long supporter and volunteer as Board Member and Officer for several music and cultural organizations.
Copper’s studies began in mathematics at the Massachusetts Institute of Technology, and as his interests turned to creating music, he moved to Philadelphia and spent two years in private composition studies with distinguished American composer George Crumb. Following a year studying independently in New York City, Copper studied music composition at the Eastman School of Music, where his composition teachers included Gerald Plain and Joseph Schwantner. A Fulbright scholarship provided Copper with the opportunity to study composition at the State Higher School of Music (Akademia Muzyczne) in Krakow, Poland with composer Krzysztof Penderecki. At the Yale summer program, he had sessions with Morton Feldman and Seymour Shifrin, and while in Poland with Witold Lutoslawski and Boguslaw Shafer, making altogether an education rarely equaled in late-20th century composition.
As a theorist of music, William Copper has special interests in formal structures and in pure intonation. His music combines perfectly singable lines in the bel canto tradition with vital rhythmic excitement and timbral subtlety. His research into the connections among musical intonation, harmony, and melodic structures, led to new operas, oratorios, symphonies, and other works for orchestra, chamber groups, and chorus.
