The Hyperviolin is the latest in a series of enhanced expert-performance hyperinstruments devised by Machover and the MIT Media Lab team. Driven by multi-channel, audio analysis and synthesis software and wireless hardware technology embedded in an enhanced violin bow, the Hyperviolin performance system gives extra power and finesse to a virtuoso player. Measurements of perceptual timbre qualities as well as musical gestures allow for the control of rich and varied soundscapes, and also allow music to be exchanged and modified between hyperviolinist and kids. Celebrated violinist Joshua Bell will play the Hyperviolin throughout the Toy Symphony tour.
