In BoomTime participants create unified music with a Boomwhacker, a lightweight, hollow, color-coded, plastic tube, tuned to musical pitches by length.

Armed with one or two Boomwhackers, they follow a visual interface which guides them in collaborating to generate a fiery symphony of music. The visual interface displays color-coded blocks across a large screen. Participants use timing and teamwork to strike their tubes and create musical notes each time a colored block hits a key.
