Matrix For Jazzers
PLEASE READ MASTER MATRIX to get an idea of how we've expanded the normal 7-tone key to include all chromatic bass tones as options.
This one plugs extended, altered, and Major/minor 7ths into the matrix.
It should be noted that this is only one perspective for composing, subbing, arranging, and whatever else you find it useful for. Traditional methods for learning jazz cadences, scales, idioms, substitutions, etc should still be internalized.
