While we haven’t learned A major yet, one of my favourite chords is Am, which you can see above. Going well with G, F, and Cmajor, Am is an excellent compliment to so many of my favourite guitar songs.
A few of them:
I recorded an Audioboo of some easy A minor strumming to hopefully provide a backing track for the beginners out there. (I accent it a bit once the recording gets going by adding my pinky finger to the high E string, in the third fret.)
