Compositions Newsome, Gregory Lee

Abstract

Seven compositions, five for live instruments and two for electroacoustics, comprise this thesis. The works for live instruments vary in genre, and include pieces for chamber ensemble, choir, and solo instrument. "Music for Solo Violin" employs thematic material modelled after Eastern European folk music and intervallic structures, as does "Bagatelle for String Quartet." "Lux aeterna" expands a small, core idea into an entire composition whose salient features are an added-tone harmonic structure and a time-varying polyphonic texture, "non-art," "The Sacrifice of Infinity," and the electroacoustic works "Chroma" and "Purity" reflect an interest in compositional syntax modelled after timbre, avoidance of a post-World War II concept of gesture, and psychoacoustics.
