Abstract
A small lightweight electronic device to indicate the note of a keyboard instrument represented by any musical interval in any key. The device has a series of on-off switches representing each of the desired musical keys and a series of switches representing the individual values of musical intervals over a desired range, preferably two octaves. The necessary circuitry is provided between these switches and a keyboard display such that any particular note represented by a musical interval of selected value in a selected key is indicated on the keyboard display. Students and teachers of music for keyboard instruments can, using this device, visualize the location of notes or chords in any key and transpositions of notes or chords from one key to another.
