I've only been playing trumpet for about 6-7 months. I don't have much of an idea of how to improve anything. I play French Horn in the highschool band (1st chair) and have a pretty descent ametuer (I have no idea how to spell that), but I'm not so sure about the tone quality. Advice on how to improve this would be greatly appreciated. Not just advice on improving tone, anything you have to say that would be of help would do me a great deal of good!
