ABSTRACT:
The present invention integrates the entire body of musical knowledge relating to key signatures, basic chord structure, the logical progression of chords within a key signature according to the cycle of fourths, identification of the root tone both of scales and of chords, the replication of chord and scale structure over the keys of a piano or the like for each consecutive octave, and the display of the most suitable inversion to use in any particular instance for a particular chord in the selected key signature. All of this information is assembled in an easily usable, flexible form having selectable key signature display panels on the left registering with a central matrix comprised of several rows of scale tones in a particular octave, this matrix being one of seven matrices pertaining to the seven octaves on the piano keyboard, with the 3rd basic element being the plurality of horizontal displays naming the diatonic scale of each pertinent key signature, these displays being selectably registerable with the matrix to correspond with the suitable vertical panel to the left of the matrix.
