Performance Support and Enhancement of the Electronic Musical Instrument Theremin by XR

Abstract

This study aims to support the performance of the theremin, an electronic musical instrument, by XR (Cross Reality) and to extend its functions. Specifically, using AR (Augmented Reality) assists in the performance of the theremin, and using MR (Mixed Reality) of sound realizes the theremin's chords virtually. The performance of the theremin, an electronic musical instrument played by holding one's hand in the air, is greatly affected by the delicate position of the hand, so AR is effective in assisting performance. In addition, the virtual realization of chords by sound MR enhances the function of the theremin as a musical instrument, which can only play single notes.
