 Matter and Motion 
This text explores the paradox inherent in the creation of music on a fixed media, also known as acousmatic music: how can we give movement to sound matter that is, by its very nature, fixed on a support? Inspired by biology, cognitive science, Bergsonian philosophy, dissipative systems and my work with choreographer Marie Chouinard, I attempt to establish an epistemological framework for my compositional practice. The text begins by briefly tracing the evolution of sound in Western classical music, and then addresses the specific challenges of writing music outside the harmonic context and the traditional instruments. This leads to the exploration of writing strategies that emerge from a phenomenological reflection on matter and movement. Certain concepts are introduced and clarified through techniques designed to make sound matter fluid and dynamic. This approach is then reframed in several of Marie Chouinard’s creations.
