Advisor: Alex Lubet. 1 computer file (PDF); iii, 124 pages.45 Minutes for 128 Musicians has demonstrated a wide range of possibilities regarding the sincere incorporation of improvisational and improvisationally-derived procedures in orchestral composition.

I finish this project expecting that the methods and technologies of modern studio production, as well as the eternal artistic migration towards new forms and new textures, will hasten the development of new orchestral textures. This production of this piece provides one such example.enCompositionThesis or Dissertation
