My kid showed an interest in learning the guitar. And I figured i could teach her basics. A family member gave us 2 acoustics. Then it occurred to me I didn't know the first thing about teaching someone to play. When I haven't played or practiced in over 25yrs and wasn't very good when I did. So I've been retraining/learning myself. Using YouTube and countless apps and teaching sites. I've paid for subscriptions and all have helped a bit. But I still haven't found the right tools.
