Abstract

In this paper, the design and construction of a new violin interface, the Hyperbow, is discussed. The motivation driving the research of this instrument was the desire to create a violin bow capable of measuring the most intricate aspects of violin technique–the subtle elements of physical gesture that immediately and directly impact the sound of the instrument while playing. In order to provide this insight into the subtleties of bow articulation, a sensing system has been integrated into a commercial carbon fiber bow to measure changes in position, acceleration, and the downward and lateral strains of the bow stick. The sensors were fashioned using an electromagnetic field sensing technique, commercial MEMS accelerometers, and foil strain gauges. The measurement techniques used in this work were found to be quite sensitive and yielded sensors that were easily controllable by a player using traditional right hand bowing technique
