Abstract: A microprocessor-based electronic guitar generates a music signal for driving an integral speaker. The electronic guitar includes a housing defining a neck and a body, a plurality of manually actuatable strings secured to the body, and a plurality of pushbuttons distributed along the neck, the strings and pushbuttons being operable by the player for controlling the composition of the music signal generated by the microprocessor. The electronic guitar is playable in a chord mode wherein the microprocessor, upon striking the strings, generates a music signal corresponding to chord sounds, a lead mode wherein the microprocessor, upon striking the strings, generates a music signal corresponding to individual notes, and an automatic mode wherein the microprocessor, upon striking the strings, generates a predetermined chord progression defining a stored melody.
