Harnessing ancillary microgestures in piano technique: implementing microgestural control in to an expressive keyboard-based hyper-instrument

The chapter describes through the implementation of microgestural sound control, how performers can gain wide control over digital sound processing through their existing technique. By using radar millimeter waves to capture micromotions and microgestures, performers achieve high level of expression without the need to modify their instrument nor dev additional technique. This research builds upon existing instrumental technique and removes the steep learning curve typically found when performing digital or augmented musical instruments. We present a case study that enables pianist to retain and focus on technical control and musical freedom resulting in a less disruptive experience.
