If you watch any good player, they're using different parts of their body and working with instruments that respond to those movements. They're moving in many dimensions at once.
Out there in the spotlight you're a million miles away and every ounce of energy you try to give away as the sweat pours out your body like the music that you play.
I was performing in this burlesque group, and we would go to dance rehearsals every day. You'd use every part of your body. Even though some of it is slow, it takes a lot of muscle to be able to dip down and come back up.
There is a strange kind of human being in whom there is an eternal struggle between body and soul, animal and god, for dominance. In all great men this mixture is striking, and in none more so than in Wolfgang Amadeus Mozart.
I grew up being into sports and I wasn't trained to move my body in the right way for dancing. I'm the last one to get any moves correct. In rehearsals it's always, 'OK, one more take for Zac.'
