Guitar

[Jason1]

So my brother got a Acoustic guitar for christmas and started taking lessons. Ive been fooling aroud with it quite a bit latley, basically having him show me the same stuff he does (which is mostly Nirvana stuff, because thats what hes into at the moment) I cant really do any complete songs yet, but so far I know the basics of Smells like Teen Spirit, About a Girl, All Apologies, Stairway to Heaven, and Sweet Home Alabama. Im probably the best at About a Girl, seems like its very easy for me to do the basic chords on that one. Anywho, a lot of those nirvana songs are mostly power chords which I seem to have trouble with. Anyone play in here? Have any tips for someone who is learning, or know any easier songs to start out learning?
