I just signed up for the free GT trial about a week ago, and decided to join. I've played guitar in a couple of punk bands and figured out a thing or two just by fiddling around with guitars. I know a handful of chords and a blues scale. But it's time I really learned how to play. I'm starting at the beginning and I've been learing a lot from the lessons. I'm hoping to learn blues guitar after I get done with the two Introductory sections.
