I started taking lessons a few weeks ago, and I feel like I'm progressing nicely. However, I have a problem fretting 2 strings with the same finger. The "A" chord is the perfect example. My index finger just can't seem to get all 4 strings down at once. The outside G string just "plunks."
My teacher says it will just take practice, but I have small fingers and am concerned! I think (in addition to practice) a mando with a narrower neck would help. My Mid-Mo was about 1.25mm wider than my instructor's Flatiron at similar positions on the fingerboard.
What do you think? Tips?
