Thanks folks. Yeah, that's the beauty of the 4 string guitar (baritone uke as well). The chords are very simple. I can remember sitting everyday at the piano, bored out of my tree, with my mother patiently trying to get me to relate to some ditty that Mozart wrote when he was three. I see nothing wrong with a kid starting to learn theory AFTER they've learned some basic skill on an instrument.(and had some fun with it.)Rick
