New musical interface for playing the guitar solo.

This paper describes the development of a new musical interface to play guitar solo with the nonstringed guitar. The previous work of authors is the implementation of the nonstringed guitar comprised of laser strings and a chord glove [J. Acoust. Soc. Am. 122, 3055 (2007)]. It is hard to express guitar solo, so voltage dividers are set up on the neck to represent frets. In the case of the chord glove, the same voltage source of the TMS320F2812 is supplied instead of attaching force sensing registers to the fingertip. Consequently, there are three essential components for the proposed interface: voltage dividers, laser strings, and the chord glove. Voltage dividers replace the six strings on the neck and send fret information to DSP, laser strings represent strokes, and the chord glove expresses playing chords and solo. This proposed interface represents many kinds of playing styles. In the case of hammering on, pulling off, and sliding, it needs fret information from voltage divider to express these things. On the other hand, bending that varies the pitch in a fret needs to detect how much flex sensors are bent to play.
