Composing Social Interactions for an Interactive-Spatial Performance System

This paper describes a recent composition, No More To- gether, in which performers’ interactions directly influence the sound of the piece. The composition provides a struc- ture for group interactions, and is performed with the on- body and in-space components of ’PESI’, an interactive spatial performance system. Our composition attempts to compose social interactions, drawing upon notions of par- ticipatory sense-making, and the idea that these interac- tions are best construed as emergent systems, possessing their own internal dynamics. The composition is contextu- alised as part of the repertoire for the PESI system, explor- ing embodied, social and spatial interactions in sound and music computing.
