ABSTRACT:
A music chart for determining the constituent tones of a plurality of chords and the chord name of a given series of tones is disclosed. The chart is comprised of a disc having at its outer circumference a plurality of spaced-apart chord names. Each chord name lies along a radius of the disc, each radius having delineated thereon a plurality of markers radially spaced from each other. A slide member having an elongated narrow rectangular window is slidably and pivotally superimposed on the disc by means of a central rivet projecting through the window. The slide member has at its lower side a graphic representation of a keyboard which is lettered according to conventional keyboard construction and includes at least two octaves. By rotating and sliding the slide member over the disc a chord name and its constituent tones are easily readable in the window.
