Deep Decline

Abstract

Deep Decline is a musical piece for chamber ensemble and interactive computer-generated sound that uses custom motion-sensing devices for controlling sound transformations. The work focuses on organic integration of playing the instrument and influencing audio processing, combining improvisation elements, computer-assisted composition, accelerometer sensors, and live sound transformations. Deep Decline was premiered by Ensemble Dal Niente on October 30, 2015 in Seattle, Washington. This document describes the creative process leading up to composing this piece, as well as preparation of the performance with the musicians. Conceptual and technical aspects of the motion-sensing devices and computer-generated sound are documented, enabling future implementations of the technologies used.
