I agree with FIonas. Sometimes there are battles worth fighting, and others that are not. I guess what would be the point if talking to the teacher, if she is intimidating it maybe more trouble than its worth - absolutely if it happens again I would go to the school, but as a one off, I would try to help your child realise that sometimes people make mistakes and sometimes its important to to let things go - also you can't jump in to fight her battles for her after the situation happens all the time. Unless its really big and she is being hurt.

But at the same time it doesn't hurt to say to the class teacher "I think there was some misunderstanding yesterday with the music teacher and my DD was very upset last night, and I just wanted to let you know" rather than going in guns blazing and trying to get to the bottom of it... Cause to be honest, you won't. There is always two sides, and while I too think it was a misunderstanding teachers are busy and sometimes kids just need to let it go and listen. Not fair. But life often isn't, and I really believe its our job as parents to help kids cope with the unfair, not protect them from it or fix things.

IMHO

sucks to see your little one so upset though, ill bet
