Ortus Ritter, Martin


This thesis entitled Ortus, for chamber ensemble, interactive electronics, and motion tracking, establishes a novel approach to spectral composition. It is scored for flute/alto flute, clarinet/bass clarinet, bassoon, piano, percussion, violin 1, violin 2, viola, cello, and real-time electronics. A conceptual narrative transforms the abstract spectral data into a story telling device through the inherent meaning and semantic implications of the chosen sound files. Ortus relies on the recording and analysis of a heartbeat as its foundation; the heartbeat is used as the musical material for the three tutti movements, with extracted pitch material used to create formal and conceptual cohesion between all of the movements. Additionally, two conceptually different sound file families are integrated, which form the basis for the small ensemble movements and are used for the creation of all pitch, structural, and formal materials.
