The Glass of Imagination is a group improv piece where performers trigger video samples of singing wine glasses and bells ringing that are tuned to different microtonal pitches. It can be performed on multiple devices online by up to 4 people (or more). Audiences can also contribute to the sound environment with their phones. The videos also include chimes, guitar noise, and insect sounds. It can be performed on laptops, phones and other devices whilst sitting, walking and/or while singing.
