Functional Orchestration

“Orchestration has been mainly taught in a quite intuitive and non-verbalized musical way, and treatises in orchestration are mostly treatises on instruments. Since the 90's, under the name functional orchestration, the composer and orchestration professor at the national Paris conservatory, Marc-André Dalbavie (1961–), and a few of his former students have developed some general and verbalized principles of orchestration, mostly based on acoustics, psychoacoustics and common practice. I briefly present some of these functions and a few related examples from the literature.”
