NTM, can't really argue the logic. The term Classical is really a misnomer. Any one can call what is before me or you as classical, especially of merit. And, frankly, that's correct. Classical chords means, I guess, Western harmony or it's notation. Bach, sort of, created or started a means to analize supposed passing tones. As more theorists got involved, and American became real, things went kind of askew, theoretically. That's where we are now. Working out the bumps. There are going to be lots of views. That's where we are. 20 years from me, the theory will become standard. Still correct, but a good and reasonable working tool for the average musician and guitar player.
