Thanks for the ABC, Jack. It's nice of you to post it.

I tried making up an accompaniment to the tune, but nothing pleased me, so I let it go.

'One thing that an awful lot of people don't seem to understand about modes is that you're not stuck with only the white keys on the piano.'

True, Don. The modes apply to any key there is. It's just that it's easier to talk about the white keys.

Does anybody know if ordinary, working musicians (such as monks using those small keyboards I see in fine art) used the modes in everyday life? Or were the modes just theory known to a few?
