I always spend the first hour of guitar practice doing reading exercises, scales and a couple of classical pieces followed by "Classical Gas". I spent a long time trying to learn Villa-Lobos "Choros No 7". I can play it but not well on steel strings. I felt I was improving when I got up to playing it at any tempo at all. Depressing really. Any talented young sixteen year old would knock it off in weeks! There's lots of players like me out there. We will never become good, but we might get better.
