An electronic music system for computer-controlled interactive p ractising and learning to play a guitar (10) includes a transducer (16) which is detachably securable to the guitar and generates analog signals representing the playing of the guitar, an interface (20) for converting the analog signals to computer-processable digital signals, and a computer (24) 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 an audio output (5) and a video output (26) 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. |
