Hyperviolin Bow


A new violin bow has been developed that can measure intricate aspects of violin technique: the subtle elements of physical gesture that immediately and directly impact the sound of the instrument while playing. A sensing system was implemented to measure changes in position, acceleration, and the downward and lateral strains in the bow stick; these sensors were fashioned using electromagnetic field sensing, MEMS accelerometers, and foil strain gauges. The resulting system is wireless and may be used to play an electric or acoustic violin. It can be used to exploit aspects of traditional violin bowing technique to allow sophisticated control of audio effects on the amplified sound of an electric violin, as well as synthesized sounds. New research focuses on calibrated measurement and analysis of bowing parameters in common bowing techniques and styles and the corresponding changes in the audio produced.
