Robert Daniel Morris (born October 19, 1943) is an American composer and music theorist. Work in music theory As a music theorist, Morris's work has bridged an important gap between the rigorously academic and the highly experimental. Born in Cheltenham, England, in 1943, Morris received his musical education at the Eastman School of Music (B.M. in composition with distinction) and the University of Michigan (M.M. and D.M.A. in composition and ethnomusicology), where he studied composition with John La Montaine, Leslie Bassett, Ross Lee Finney, and Eugene Kurtz. At Tanglewood, as a Margret Lee Crofts Fellow, he worked with Gunther Schuller. Morris has taught composition, electronic music, and music theory at the University of Hawaii and at Yale University, where he was Chairman of the Composition Department and Director of the Yale Electronic Music Studio. He was also Director of the Computer and Electronic Studio, Director of Graduate (music) Studies, and Associate Professor of Music at the University of Pittsburgh. In 1980 Morris joined the faculty of the Eastman School of Music where he currently teaches as Professor of Composition. (He was chair of the Composition Department from 1999–2005 and before that a member of both the composition and music theory departments.) Other teaching posts have included positions at the Philadelphia College of the Performing Arts, the Governor's School for the Arts held at Bucknell University, the University of Pittsburgh Computer Music Workshop, and the Berkshire Music Center at Tanglewood. Written works Musical compositions Morris has written music for a wide variety of musical forms and media. He has composed over 160 works including computer and improvisational music. Much of his output from the 1970s is influenced by non-Western music and uses structural principles from Arabic, Indian, Indonesian, Japanese, and early Western musics. While such influences are less noticeable in his more recent works, the temporal and ornamental qualities of Eastern music have permanently affected Morris's style. Moreover, Morris has found much resonance among his musical aesthetics, his experiences in hiking (especially in the Southwestern United States), his study and appreciation of Carnatic Music of South India, and his reading of ancient Indian, Chinese, and Japanese Buddhist texts. Among his present compositional projects is a series of the works to be played outdoors in a natural setting. Seven of these works are complete and have been performed: Playing Outside (2000), Coming Down to Earth (2002), Oracle (2005), Sound/Path/Field (2006), Arboretum (2009),
