Like Electric Light Orchestra, Deep Purple, The Doors. I've been playing guitar for aobut 2 and a half years and am pretty good at that, but want to broaden my horizon. I don't really want to take lessons, maybe like a tutorial site. I know a broad GENERAL music theory, major scale construction, chord construction, some modes, etc. Any help?? Thanks, and I really am committed to this. It's not just a passing whim.
