C and G major scale
practice this scale a few times as a warm up. Make sure to press down with the fingertips and try not to bunch up your fingers
Aura Lee
practice each line in groups of two bars. The second line is a repeat of the first, so no need to practice it!
Chords
work on the checked chords. For the more difficult chords, just play the first three strings of the chord
Three Little Birds
try working on the first line and playing along with the recording if you feel comfortable enough
