Abstract: A transducer assembly for an electronic music system for use with a stringed instrument includes a plurality of transducers and a quick connect device for detachably securing the transducers to the stringed instrument without marring, defacing, or altering the stringed instrument. The transducers generate analog signals representing the sound generated by playing the instrument. An interface converts the analog signals to digital signals and a computer receives and processes the digital signals. The location of the transducer assembly relative to the strings of the instrument is adjustable.

Abstract: An electronic music system for computer-controlled interactive practicing and learning to play a guitar includes a transducer which is detachably securable to the guitar and generates analog signals representing the playing of the guitar, an interface for converting the analog signals to computer-processable digital signals, and a computer for receiving and processing the digital signals. The system uses a communication protocol which employs time stamping of data to permit use with ordinary guitars but without high speed frequency determination. The computer provides audio and video outputs including staff and guitar fingering representations of notes, chords, scales, compositions, and like musical structures, both to teach the user and suggest music to be played by the user and to illustrate what the user has played. The system is operable in several modes which may be controlled by the user by signals produced at the transducer.
