Thanx bro. It's explained some things, I still can't see a basis of theory on it. Even more a reason to discard any part of music, because even a simple C note is out of tune with itself. Making a simple chord out of it, C5 is just horribly out of tune if you pay attention to these harmonics and base these strict views on it. The idea of harmonizing over a C note with a G would cause harmonics in every pitch, even out of tune pitches. It looks like there is no satisfaction from this analysis. That's just how I see it.

It's impossible to get rid of, even the harmonics of a note change with a different instrument (even 2 different guitars). The harmonics that sound make up the note sounds, like a group of pitches make one singular fundamental pitch. If you got rid of all the harmonics and only heard the fundamental, it would be like looking a picture in only the color white.

I really just seem to be another over-analyzed theory to try to give perfect stability to music. If it helps some that's kool, but music is about hearing not science. You could easily go through life just playing the chord progression I - vi - IV - V7 because it works and science allows it. Why can't you play a chord progression like i - vi(hd) - ii(hd) - V7 (hd - half-diminished). Alot of theories will say this won't work or whatever, but it sounds awesome! Isn't that the point, what sounds good not what theory say you can or can not do??
