Thanks Aaron; when you talk about examples, do you mean specific songs that use these techniques, or actual spelled out examples (like giving notes).
As a side note, does anyone know a good way to incorporate actual music notation into a document? I suppose I could make jpegs with a notation program, but what a hassle!
As for the breaking the rules thing... yeah, it's kind of implied whenever you write a theory text. I thought about it, but you know, if I put that in every theory article I wrote it'd get tiresome. I'm working on a full-blown theory primer that says a bit about that anyway.
I've found that most of the time, when people "break the rules", they aren't really breaking the rules, they're just using a somewhat more advanced rule that most people don't know about. I guess there is some genuine rule-breaking out there, though; I did mention grunge using parallel 5th vocal harmonies.
Besides, I don't know too many musicians who respect authority enough not to at least TRY breaking the rules now and then.
