Composing Social Interactions for an Interactive-Spatial Performance System

This paper describes a recent composition, No More Together, in which performers’ interactions directly influence the sound of the piece. The composition provides a structure for group interactions, and is performed with the onbody and in-space components of ’PESI’, an interactive spatial performance system. Our composition attempts to compose social interactions, drawing upon notions of participatory sense-making, and the idea that these interactions are best construed as emergent systems, possessing their own internal dynamics. The composition is contextualised as part of the repertoire for the PESI system, exploring embodied, social and spatial interactions in sound and music computing.
