Augmented Reality offers great potential to support musicians in collaborating remotely. We are building an application to enable drummers to play together in a drum circle using physical electronic drum pads and augmented reality technology. Unlike previous remote jamming applications, musicians who use this application will see AR avatars of each of the other drummers they are playing with (up to two other drummers) which they can place in their own environment via AR fiducial markers. Audio will be captured via the MIDI output from the electronic drum pads and sent to each musician in the circle, where it will be synthesized into spatial audio based on the placement of the avatars. Combining the MIDI output with hand tracking, we will enable players to communicate through body movement with their avatars, a core component of music collaboration.
