Body as Instrument explores how musicians interact with movement-controlled performance systems, producing sounds imbued with their individual physical signature. Using motion tracking technology, performers can translate physical actions into sonic processes, creating or adapting novel gestural systems that transcend the structures and constraints of conventional musical instruments. Interviews with influential artists in the field, Laetitia Sonami, Atau Tanaka, Pamela Z, Julie Wilson-Bokowiec, Lauren Sarah Hayes, Mark Coniglio, Garth Paine and The Bent Leather Band expose the transformational impact of motion sensors on musicians' body awareness and abilities. Coupled with reflection on author-composed works, the book analyses how the body as instrument metaphor informs relationships between performers, their bodies and self-designed instruments. It also examines the role of experiential design strategies in developing robust and nuanced gestural systems that mirror a performer's movement habits, preferences and skills, inspiring new physical forms of musical communication and diverse musical repertoire.

The author presents Probatio, a toolkit for building functional DMI (digital musical instruments) prototypes, artifacts in which gestural control and sound production are physically decoupled but digitally mapped. He uses the concept of instrumental inheritance, the application of gestural and/or structural components of existing instruments to generate ideas for new instruments. To support analysis and combination, he then leverages a traditional design method, the morphological chart, in which existing artifacts are split into parts, presented in a visual form and then recombined to produce new ideas. And finally he integrates the concept and the method in a concrete object, a physical prototyping toolkit for building functional DMI prototypes: Probatio. The author's evaluation of this modular system shows it reduces the time required to develop functional prototypes. The book is useful for researchers, practitioners, and graduate students in the areas of musical creativity and human-computer interaction, in particular those engaged in generating, communicating, and testing ideas in complex design spaces.
