Verily, Dick! I didn't know that was you.

Be of good cheer, M.Ted. It's not all that complicated, but trying to explain it verbally is what makes it seem complicated. I have been able to teach this stuff to a class of beginning guitar students (eighth class in a course of ten) with guitar in hand, demonstrating, then having them try it. They got it! Duck soup!

As I say, it's not as complicated as it looks when laid out on these threads. Wrong medium!
