Watch the Hand Size online guitar lesson by TrueFire from Play Acoustic Guitar 5: Fingerstyle Principles
Hand Size - Overview is a video guitar lesson presented by Tommy Emmanuel and is sourced from Fingerstyle Milestones.
A lot of people come to me and say that they can't play that type of song because I don't have big hands like yours, or that they don't have guitar player hands. I don't buy any of that. I'll tell you why. Because there are people in this world who have tiny little hands, like little children. I've seen so many young children, six, seven eight years old, who are playing guitar and pulling off these things and reaching the stuff that adults have come to me and said they can't play because they don't have big hands. I tell them that it's no excuse. Small hands means more you have to be more determined. What happens with your hands is that if you keep trying it you will get it. And your hands will shape to what you need them to do. When someone tells me they can't get their thumb over I tell them to find another way of doing it. Don't let anything stop you. Don't let the fact that you have small hands stand in your way. I've always had fairly big hands even when I was a little boy. I guess I was lucky in that respect. However there are people around who can play a lot more complicated stuff than me and their hands are a lot smaller. It's really a matter of how determined you are and how committed you are to getting the job done.
