Subtlety and detail in digital musical instrument design

Full PDF available at Queen Mary Research Online.

Abstract

Subtlety and detail are fundamental to what makes musical instruments special, and worth dedicating a life’s practice to, for designer, maker, player and listener alike. While instruments are recognised and classified by form, it is the nuances of individual instruments that constitute their power to say what could not be said any other way. Digital musical instruments (DMI) have long been criticised as lacking expressive depth, but technology of sufficient fidelity now exists, which raises compelling questions. What can contemporary DMI designers learn from heritage practices about mastering subtlety and detail? What forms does this mastery take, and how can it be elucidated, compared and shared? Using DMI design tools, kits and activities as probes, this thesis addresses these questions from the perspectives of design, embodiment and craft. In a preliminary study, violin luthiers were asked about subtlety and detail in their practice and culture. The outcomes suggested that subtle details originate in the tacit and embodied realms, which are facilitated to develop by specific contexts, environments and materials. In the first study, attendees of a DMI research conference participated in a workshop reflecting on subtlety and detail. Attendees were divided into groups and explored the physical details of a DMI design kit, in an activity book ended by discussion. Responses focused on re-interpretations of instrumental identity, suggesting that the provided context motivated in the opposite direction to the original brief. In the second study, the same kit was deployed with single rather than co-located groups of digital luthiers, modifying instead the sound of the instrument via a Pure Data patch, and responses focused less on instrumental identity and more on gesture-sound mapping strategies. Provocatively, neither studies resulted in sustained focus on details, motivating a novel DMI probe and activity for individuals. In the third study, digital and traditional instrument makers, musicians and other creatives, were invited to handcraft the resonance models of a digital tuned percussion instrument using sculpting clay, responding to constrained briefs. Participants’ backgrounds deeply influenced their responses, and distinctive themes emerged related to aesthetics, tacit and embodied knowledge, and algorithmic pattern. This thesis introduces a scale-based ontology of DMI design, dividing detail into macro, meso and micro levels. Focusing on the micro scale, a series of reflections and suggestions are provided based on the investigations, for how DMI design practitioners, technologists and researchers can illuminate this domain, for the benefit of subtle and detailed digital musical expression.
