Hey all. I teach music privately. I try to make my lessons fun and an enjoyable experience for my students. However, I have one student who appears to be suffering from intense anxiety over not performing his pieces perfectly. His body get very tense when he plays. He gets mad at himself if he cannot get a particular song perfectly right if it has been assigned for a few weeks. He is doing intermediate to advanced pieces and I think he is doing fine. He constantly asks how he is doing compared to others. He is 13 years old and I'm getting worried about him.
