Abstract
Abstract An electronic device in the nature of a hand-held calculator, for illustrating on an active tablature display area, simulating a guitar fingerboard, chord shapes and scale patterns across a full twelve frets is provided. The device comprises a number of manually operable basic chord and key information dials for input selections. A microcontroller means is electronically associated with the dials and the LED's, and upon actuation, the microcontroller means searches for scale and associated finger position information corresponding to the tonality requirements of the input selections, and displays that information by way of illuminating means in the appropriate areas of the active tablature display.
