Abstract
Abstract The invention is a teaching and practicing aid for music students which graphically displays the relationship of the dominant, tonic, and subdominant scales in a particular key signature and as they relate to the diatonic scale in that key signature, the device structurally comprising a backing sheet optionally having the scale tones of a diatonic scale named in a row along the bottom, and three preferably reversible panels disposed in staggered horizontal slits cut in the backing sheet, these panels having portions visible above the slit with indicia thereon indicating by fingering number or scale tone name musical notes representing chords or scales, these notes being spaced proportionally to the key spacing of a piano keyboard. There is an optional insert card having two selectively displayable portions which represent the left and right hand, respectively, with the fingers thereof numbered in accordance with conventional elementary teaching techniques.
