This is great! Thank you all so much. I'll print this out so I can study it -- plainly will take much more of my time than I can give it tonight.

And yes, Gargoyle, jazz is something I admire, but to which I don't aspire. I only have so many years left of this earthly veil and I don't think they're enough to even begin to consider learning to *play* jazz. But to appreciate? Yes.

I've known about the circle of fifths, or cycle of fifths, but haven't had it explained to me. So I will print this out and work at learning it so I can pass Neil's pop quiz.

Gratefully, WW
