Tetrachord Matrix of Heptatonic Modes

[rm5]

This is something I just came across (actually during my last piano lesson) that I think is REALLY COOL! Basically, it's a "matrix" of all the different combinations of chromatic pitches that could be used in a heptatonic scale starting on the root.

This assumes you know the chromatic solfège syllables—if you don't, I've also attached a JPG with those, too!
