In this paper we present HIVE, a parametrically designed interactive sound sculpture with embedded multi-channel digital audio which explores the intersection of sculptural form and musical instrument design. We examine sculpture as an integral part of music composition and performance, expanding the definition of musical instrument to include the gestalt of loudspeakers, architectural spaces, and material form. After examining some related works, we frame HIVE as an interactive sculpture for musical expression. We then describe our design and production process, which hinges on the relationship between sound, space, and sculptural form. Finally, we discuss the installation and its implications.
