I move.

Playing and singing is a very physical thing for me. My wife has commented for quite a while that when I play the upright bass that I wiggle my butt. She likes that, I guess. At the end of a gig, I get that exhausted but adrenalin still flowing feeling.

But really, I feel the music I play with great passion, especially on the guitar or bass so much that I have to move with it. When I play the banjo, I move into the mike quite deliberitely when it is my lead. I believe audiences want and like this kind of animation. As for stoic bluegrass bands, quite the contrary when you see the Del Mcoury band working with one mike. The choreography is amazing.

Also, when I do harmony parts in a group, the stepping up when that chorus starts adds a lot more to performance dynamics. Watch how cool it's done by Ricky Skaggs and Kentucky Thunder if you get the chance.
