I feel that this is by far the hardest week of the whole 6 week study. Mainly because we are learning the D chord and it’s an awkward chord change. The good news is that the next two weeks the chord changes are going to feel like a walk in the part after everyone gets the hang of the D chord.
During the practice between G and D, practice leading with your second finger. I show this on the practice video session. Leave all other fingers in place and practice moving just your second finger.
You will also have to make an extreme TILT in your left hand to get the D chord to sound right.
