Well damned Flugelgirl.
You're a girl and a pretty one at that.
Here's the problem. You don't look anything like the basic trumpet player. We need to change up your diet so in a year or so we'll have you looking the part.
But seriously, I have a daughter that plays trumpet (10yrs.old) and I'm her teacher. I take the time to tell her she's great when she plays great and tell her when it sucks when it sucks. I also take the time to tell her she's pretty. She tells me she's going to beat me at trumpet some day. Of course I raise my eyebrows and tell her, "I don't think so". Trumpet is an equal opportunity instrument and anyone who doesn't think so needs to get their stone aged head out of their ass and get with reality. I also advocate that girls learn martial arts for those occasions when boys decide to get stupid.
