Remember, just because you know three chords doesn't mean you have to push yourself to play songs using three chords. Let's stick with those two-chord songs for today, and you can pick either A and E, or D and A. Either will work for most of those two-chord songs on our list.
If you choose a song and use A and E, but it doesn't sound quite right or it's hard for you to sing in that key, try using D instead of A, and A instead of E. Remember to take a good listen to your first chord before singing the melody, as that will serve as your reference note for singing the melody.
Also, we have a few rhythms down now, so let's try to ease those into our playing. Perhaps a little folk/country, or maybe a reggae groove. There's no rush and don't feel frustrated if you don't get it at first, you will, I promise!
