Ive been playing guitar for about 2 months now, i can play fairly well but the one thing that stops me me from not making a fool of myself is relaxation problems. No matter how hard i try im always screwing up my face in concentration and poking my tounge out etc. Has anyone else had this problem and possibly know ways that i can prove on my relaxation when playing guitar?
look some one in the face. Preferably a good friend or your girlfriend. It usually works for me.
Watch TV? Learn how to do it without looking at your hands. That's about the only advice I can give you. Learn what you're playing to the point where you don 't have to think about it - then, concentrate on keeping your face normal.

Just like playing and singing at the same time, really. One thing at a time.
It's true the more relaxed you are, the better you can play. I've struggled with that since I started playing, and while I'm getting better, I'm far from mastering.
Away Message: I fell out of my chair, this may take awhile.
