Abstract

Evolve is a c. 16 minute work for full orchestra that explores various ways in which a single hexachord can be used to govern a variety of aspects and parameters within a work across multiple levels of structure. This includes melodic, harmonic, durational, temporal, textural and even formal aspects of the work, all derived as expansions, reinterpretations or explorations of specific relationships found within this collection of pitches. These relationships include the inherent intervallic and harmonic content found within the collection, but also extends to the frequency ratios found between pitches in the hexachord. In total, the piece is comprised of nine sections, each of which explores one or more applications of these expansions/interpretations.
