Alec, I got a chuckle out of your answer, too. I've noticed the chord modify change, and I've seen you mention it, but since I didn't know what it was, didn't use it, I just didn't bother with it, or even try to learn more. Now you have my interest up, so I'll turn to page 49, give it a read and see if I can make something of it. I don't wander far from the music sheet when I play, but there have been too many times when the chord change has been jerky and odd sounding, so maybe this has been the answer all along. Once again, you've shown the way!
