(b Bern, Idaho, 1935).
Amer. composer. Founded Theatre of Eternal Music, 1962. Method of composition may be deduced from his directions for perf. of certain of his works: Composition 1960 #2 is building a fire in front of the audience; #5 is releasing butterflies; Composition 1961 is ‘draw a straight line and follow it’. Has also ‘written’ The Tortoise, his Dreams and Journeys, a continuing perf. (since 1964) for vv., mixers, amplifiers, drones, and loudspeakers (but no tortoise). The Well Tuned Piano (1964), written for prepared pf., can be considered his most important work. He has perf. it on many occasions, the perf. lasting over 6 hours.
