WOW Chris. Thanks for getting back to me on this. I've never gotten much into this Chord Theory in the past but have some understanding of the CIRCLE of 5ths from my years in Acapella Harmony (Barbershop). I found Lisa's Tool on Chord Theory helpful in solidifying my foundation on the subject of chording arrangements.

Glad to see even this subject is not so structured (ak Black and White), thus allowing the artist to have the perogative to exercise artistic enhancement to his arrangement.

Thanks for such a thorough explanation.
