Abstract: A keyboard-based device for simultaneously reading and playing music on the basis of the conventional written score thereof is disclosed. The device includes a microcomputer and a graphic tablet for holding a paper sheet or a set of score sheets to be processed sequentially, and recognizing any X and Y axis position of the score touched by the tip of a pointer handled by a performer. Each of the graphic tablet X and Y signals thus activated is transmitted to the microcomputer, which has software preprogrammed according to the score in question. Programming is such that any X-Y pair activated on the page triggers a signal that initiates a signal stream for inputting into a sound generator optionally built into the device. The generator then outputs the note closest to the contact point with the pointer on the score.
