Super helpful for a beginner
I’m working through this as an adult with a guitar teacher. It’s been very helpful for getting some basic concepts down.
What it doesn’t have in spades is a lot of form and technique stuff, but in general if you want to be GOOD at this you’ll need someone to help you build good playing habits and develop your technique.
