Schoenberg and adherents have nothing that helps ME make popular western music, although it does work for movie backing tracks and such. To me, there's no beginning, no middle, and no end ... just a string of unrelated passages. Yes, I know ... it's because I'm not hip enough to appreciate his genius ...
So for me, this is just useless academic theorizing ... and has little use in composing western music of any ilk, and even less when demonstrated on guitar. Shoenberg thought he was ushering in a new way of thinking about music ... and was disappointed that it never had the impact he had hoped.
Give this a listen ...

Nothing takes the music out of music more than
useless theory. (IMO, of course)
