It sems whenever I play in certain settings I just end up regretting it. I can play fine infront of the concert band (in rehersals) and in lessons or in a group. But, I have a hard time in other settings no matter how much I practice the piece. Espacially in a small roomwith family, friends, etc. I try not to worry very much about messing up and I try not to. I am not usauly shy or anything. Any suggestions?
