Instrumental Listening: sonic gesture as design principle

Abstract

In the majority of discussions surrounding the design of digital instruments and real-time performance systems, notions such as control and mapping are seen from a classical systems point of view: the former is often seen as a variable from an input device or perhaps some driving signal, while the latter is considered as the liaison between input and output parameters. At the same time there is a large body of research regarding gesture in performance that is concerned with the expressive and communicative nature of musical performance. While these views are certainly central to a conceptual understanding of ‘instrument’, it can be limiting to consider them a priori as the only proper model, and to mediate one’s conception of digital instrument design by fixed notions of control, mapping and gesture. As an example of an alternative way to view instrumental response, control structuring and mapping design, this paper discusses the concept of gesture from the point of view of the perception of human intentionality in sound and how one might consider this in interaction design.
