ABSTRACT:
A set of hand-held plastic laminated disks which provide for visually displaying selected combinations of musical information such as musical notes of scales and chords. The display is composed of two disks. The top disk functions as a template and is fastened to the lower disk at the center by a metal eyelet. The lower disk displays the twelve notes of the chromatic scale on several concentric circles. Apertures on the top disk display subsets of the chromatic scale as diatonic scales or chords. By rotating the bottom disk relative to the top disk, the notes of all twelve diatonic scales and their associated chords are displayed.
