A theory headed friend pointed me in the direction of this article on symmetric harmony, link below

So, after reading it, doing some thinking, and being astounded at what an amazing idea it is. I got round to listening to A Love Supreme again ...and I can actually him moving a melody through symmetric tonal centres.. I can actually hear it
For me, this is a revelation!!
That's all really, just thought I'd share

The article is very good, although the written English isnt perfect, it's still clearly explained
cheers
