What a lot of people sometimes forget is that the guitar is an instrument that plays music. I mean, when learning, it is not only important to learn to play the instrument but also learn musical theory aside from that. For doing that, in addition to learning things on the net, just go to the library and borrow a book, not on guitar, but on music theory in general. This will really help put things together and make a person not only a better guitarist, but a better musician.
