Beginning Rock Guitar

I've been teaching my youngest son guitar for a couple of years. We're going through some standard "method" books for the basics and a good foundation in reading. There are so many great teaching resources that didn't exist when I was learning (back in the Dark Ages). He's now starting Beginning Rock Guitar, the first in a series of three, from National Guitar Workshop. It comes with a CD so he can hear how each exercise is supposed to sound. I'm glad I've been given the patience to stay with this- for his sake, and mine.
