Thanks Helen. I checked out three lessons, and though I think I'm beyond most of the theory there, I'll take the tests to make sure. The site appears to be well-written, and I really appreciate that.
And since I don't have $40 to burn, the next time I'm in a music store I'll steal a peek at the Ultimate Broadway Fake Book to see if my chord selections were the same. The catter who requested them was pleased and graciously thanked me.
