American composer Roger Reynolds was born on July 18, 1934, in Detroit, Michigan. At age 14, he determined to study piano after hearing a recording of Chopin's Polonaise in A-flat major, Opus 53 played by Vladimir Horowitz. Even though his piano teacher Kenneth Aiken recommended that he continue his study at the Curtis Institute of Music, Reynolds followed the suggestion from his parents that a musical career was not practical. After receiving a bachelor degree of engineering physics at the University of Michigan, he worked in the industry for a short period of time. In 1957, he returned to Michigan and resumed his study of music by taking a class called Composition for Non-Composers under the instruction of Ross Lee Finney. Reynolds continued his compositional study with Finney and Gerhard who were influenced by the Second Viennese School until he finished the master's degree (B.M. 1960, M.M. 1961). Variation was written under the auspices of The Banff Centre for the Arts in 1988. This piece was dedicated to Peter Serkin and premiered by Alec Karis, a faculty member at UCSD, on December 3, 1991 at Merkin Concert Hall, New York. This large-scale set of variations for piano is one of the rare instances in which Reynolds used a conventional genre. What concerned Reynolds most in Variation was "the notion that transformations of meaning could occur entirely as a result of changes in context." He designed this variation as five sections -capriccioso and I, grave and II, III, scorrevole and coda. Capriccioso, grave and scorrevole also refer to the three basic thematic elements of this piece. These three main themes appear throughout the whole piece employing fragmentations or superimpositions. Reynolds used two computer algorithms (SPLITZ and SPIRLZ) to make transformations on these three thematic ideas. He cut the themes up into small fragments, and then recombined these fragments into a kind of altered mosaic. This process resembles his experiments on words: he disassembled words into elementary figures (dots, lines, etc.) and gathered them into new figures, i.e. new words.

Watershed I/IV, for Solo Percussion and Real-time Computer Spatialization was composed in 1995 by Pulitzer prize-winning composer Roger Reynolds. This work is a 25-minute choreographed music drama for one multiple-percussionist, in which Reynolds incorporates the musical transformation of percussion instrument families, the physical gestures of the performer, and the spatialization of processed sounds around the audience. This dissertation addresses several aspects of Watershed, which include: the expressive intent and extra-musical concepts; the formal organization, and several non-musical tools that Reynolds utilized in designing the piece (e.g. logarithmically derived sequences); the primary musical motives; the instrument setup and how the resulting physical gestures contribute to the musical intent; and the real-time computer spatialization. Throughout the document, specific musical passages are demonstrated with notated musical examples and embedded video/audio clips. In addition, transcripts of my interviews with composer Roger Reynolds, percussionist Steven Schick (premiere performer of Watershed) and engineer/technician Greg Dixon (engineer for my performances of Watershed IV) are also included.
