This research explores virtual reality as a medium for live concert performance. I have realized compositions in which the individual performing on stage uses a VR head-mounted display complemented by other performance controllers to explore a composed virtual space. Movements and objects within the space are used to influence and control sound spatialization and diffusion, musical form, and sonic content. Audience members observe this in real-time, watching the performer\u27s journey through the virtual space on a screen while listening to spatialized audio on loudspeakers variable in number and position. The major artistic challenge I will explore through this activity is the relationship between virtual space and musical form. I will also explore and document the technical challenges of this activity, resulting in a shareable software tool called the Multi-source Ambisonic Spatialization Interface (MASI), which is useful in creating a bridge between VR technologies and associated software, ambisonic spatialization techniques, sound synthesis, and audio playback and effects, and establishes a unique workflow for working with sound in virtual space
