They are okay for a very beginning guitarist but a little more difficulty would be great. I expanded on a few of them and they sound good but I would like to see more of a difficult progression. Like I say though this is the best site I have found on the net yet and I have been playing over 40 years. It has brought be full circle to things I used to know but forgot and even taught me things I hadn't really ever knew. This site is GREAT!!! :) :) :)
