do you know the chords? Can you find them?
Don’t worry if it gets too confusing. Here’s an easy method.
Learn to play Em. Stick to that for a day or two, just strum holding those two fingers until you get blisters.
Now learn Am, and play “Lady in Black” for a few days.
Now learn E, and play E/Am in different variations for a week. Practice changing between them fast, both ways.
Now learn Dm. It’s pretty tricky. If your fingers can’t do it, go back a couple of steps and try again in a few days. When you’re ready, try a minor song using Am,Dm and E. You can also learn E7 now if you want, and use that instead.
Now learn A and D (or A7 and D7) and play some Blues and Rock ‘n Roll on A. The chords you need are A,D,E. Stick to this for another month, and concentrate on the right hand (different strumming patters, stops etc).
Then learn the rest in this order: G, C, F, B7, F#m, Bm, (Gm, Cm etc). You now know enough chords to basically play any song in the world. Enjoy! :)
