learn how to play basic chords, such as g, e minor, a, a minor, c, d, and e. make ur own rythems with those chords, and learn to switch between each chord smoothly. if you like rock, learn power chords. also learn to fast pick. i learned that in like ten minutes ;). (bragging rights). then learn to play ur favorite songs. the most important things to learn are:basic chords; finger strumming/plucking; power chords (if you like rock); fast picking (also if u like rock ;). when you learn that, start learning to play bar chords, and all of the rest of the chords. im telling you IF YOU WANT TO LEARN GUITAR REALLY REALLY FAST, MAKE YOUR OWN RYTHEMS AND LEARN TO SWITCH BETWEEN YOUR CHORDS. dont follow rythems in books or lessons, unless they are simple eighth notes or quarter notes. im tellin ya, MAKE YOUR OWN RYTHEMS YOU WILL BE GOOD FAST. OK? sorry im bein a little rough, but hey, thats what u gotta do! im tellin ya, i started guitar this christmas, and i am very very good now, and i never went to a single lesson. (bragging rights again). i hope this was helpful. if i were u, id start out with an accoustic guitar.
