Hi JohnM & Waxwing-
Thank you both for the link and for the Tag Index tip. I too enjoy Pre-Blues material quite a bit, and that thread is an interesting one. I struggle with some of the musicology mentioned- I have to really turn on the brain when reading about it. I work a little better when I can see the differences of what exactly is being played...but I'm working on it.
Additionally, I've always felt a little uncomfortable singing blues lyrics. It's not the genre, but more of the lines that include some form of "I've got the ______ Blues." I prefer to sing songs without these lines, and I often will eliminate the line of a song that may contain it.
Take care
