This will take some time to explain. I will make it unscientific as possible. (cents and such) Be patient, summer is my work time, don't have much. For example;
"Dominants moving anywhere
Again you misunderstand me. I’m talking about what notes are not good to harmonize over a dominant chord, not altering it. Like a D# (#5) over a G dominant 7 chord. Doesn’t sound good at all."
Totally an abjectly incorrect. I don't get it. It depends upon where it's going. It sounds perfectly fine, to me. If you play a chord, and then play a scale that is altered such as G7, (D#, your view, b13, Eb, my view) sounds perfectly ok. #5 sounds correct, to me. Function is the key and ultimate resolution. Any note can harmonize over a dominant chord. Write your triads out.
A lie goes around the world before the truth gets it's shoes on. (Mark Twain)
