Three indicator strips are used alternatively to indicate from these scale tones those which are used in the tonic, dominant, and sub-dominant chords, respectively, of a particular key signature, the inversions of these chords being named on a rotatable dial, and worksheet-type writing paper being optionally provided behind said panel whereon the student can inscribe the scale tone names of any particular chord.
