Thanks, Spaw. Seed, I have read that book but it's not quite what I'm up to now. Sure would be a great project for students or just to show to them. So you teach music? I'm in the midst of a major decision about my career. I think I will always be frustrated to the max teaching high school, so I think I'll switch to elementary. I found that I only have to take two or maybe three courses to be certified in elementary. Maybe I can do more good if I get to them younger. Thanks for your info and thoughts.
