This paper describes the implementation of the non-stringed instruments using the TMS320F2812 DSP, which is possible to produce the sounds of musical notes. This basic concept of the instrument comes from the non-stringed instruments, which is not necessary to tune the string of the instruments before starting the play. In this paper, this system chose the guitar as an example for implementation. The system does not need a guitar body, but the pickup part is needed. The pickup of the system plays an important part in representing the up/down strokes and arpeggios. Therefore, the proposed system consists of three parts: Chord glove, pickup, and processor. Mapping between guitar chord and the glove takes place on the values of the force sensing resister and FLEX sensors. The extension of this system can be applied to stringed instruments in the future.
