I took three years of music theory at the University of Washington School of Music. One of my professors was composer-in-residence John Verrell, one summer of private lessons with composer Mildred Hunt Harris, then another two years at the Cornish School of the Arts (a conservatory). Cornish also offered courses in the physics of music, which I also took. (This, along with singing and classic guitar lessons). So I can speak with some degree of authority.

josepp, the wheel was invented a long, long time ago.

And there is nothing mystical or occult about it.
