I've been having this problem for a couple years. When ever I play for someone, like an audition or just for family (sometimes even at my lessons), I just can't play relaxed. I always start shaking and stuff like that. I try not to worry about technical stuff when I perform, but then I mess up somewhere, and my whole performance is thrown off. I know that I can play the pieces and have had many very successful auditions, but I still freak out whenever I play for someone. Now I have college auditions and a chance for the Cleveland Orchestra Youth Orchestra principal chair. I was hoping anyone knows of some good ways to calm down for these things.
