Fine. But I'm saying if you want to actually understand how music works (rather than play an instrument) the standard notation IMHO actually gets in the way.

Because the most important thing is the actual semitone intervals, and the standard notation hides them and gives them weird names like augmented fourth (it's just six semitones, just call it that). And it names the 12 semitones based on the c major mode even though that's only one of about 50 modes/scales/keys you might want to use.
