Implementation and development of sculptural interfaces for digital performance of music through embodied expression

This demonstration paper describes the conception, design and implementation of a hardware/software musical interface and its use in performance with a group of dancers and a choreographer. It investigates the design and development of such interfaces in the light of these experiences and presents material from two of these custom interfaces. The work examines the nature of digital interfaces for musical expression through the use of multiple sensors, the data from which is used to generate and control multiple musical parameters in software. This enables levels of expression and diversity not generally available using conventional electronic interfaces, the latter frequently being limited to the direct control of a limited number of musical parameters. The combination of hardware design and algorithmic manipulation combined with the expressive potential of dance and embodied movement is of particular interest. Reflecting links between embodied movement and expression in live performance, the feedback between form and function is also considered, as are collaborations with sculptors to develop and enhance the physical behaviour and visual appearance of these devices.
