Frederic Anthony Rzewski (born April 13, 1938 in Westfield, Massachusetts) is an American composer and virtuoso pianist.
Rzewski (pronounced zheff-skee) began playing piano at age 5. He attended Phillips Academy, Harvard and Princeton, where his teachers included Randall Thompson, Roger Sessions, Walter Piston and Milton Babbitt. In 1960, he went to Italy, a trip which was formative in his future musical development. In addition to studying with Luigi Dallapiccola, he began a career as a performer of new piano music, often with an improvisatory element. A few years later he was a co-founder of Musica Elettronica Viva with Alvin Curran and Richard Teitelbaum. Musica Elettronica Viva conceived music as a collective, collaborative process, with improvisation and live electronic instruments prominently featured. In 1971 he returned to New York.
In 1977 Rzewski became Professor of Composition at the Conservatoire Royal de Musique in Liège, Belgium, then directed by Henri Pousseur. Occasionally he teaches for short periods at schools and universities throughout the U.S. and Europe, including Yale University, the University of Cincinnati, the California Institute of the Arts, the University of California, San Diego, the Royal Conservatory of The Hague and Trinity College of Music, London.
