Ah! Thanks for clarifying that for me, Jack and Don. As an American, I assumed the "moveable do" mentality, and I thought it was universal. Never heard of the concept of a "fixed do" before. From Don's explanation, it sounds synonymous with the "all white keys" concept.

I guess you could adapt the Nashville numbering system to modes... but that also would lead to confusion ("the IV chord in the VI mode" -- eek!).

Awwwrighhht, I'll learn the Greek names *mumble grumble whine* (shuffling feet with head bowed)
