Attention to the role of the body and bodily awareness in human-computer interaction is increasing. Broader availability of cost-effective motion sensors in mobile and gaming applications has prompted a shift to body-centered design methods. This article examines the relevance of embodied sketching activities drawn from soma-based and sonic interaction design to digital musical instrument (DMI) development. It focuses specifically on the Telechord, a novel motion-controlled system that promotes methods for exploring connections between movement and sound. By emphasizing the felt aspects of movement-based design and performance, this approach places performer experience at the forefront, complementing technical efforts to enhance nuance and coherence in current DMI design research.
