Hello fellow yahoo answerists!. I have a problem, but first i will give you a description!. My band is a marching band similiar to Corps etc, and we are pretty small, but we compete with bands like Lafayette High School from Louisiana, which went to BOA and placed 15th!. We have some GOOD instrumentalists and some not so good!. I played mellophone my sophomore year, and junior year i did the pit because we didnt have enough people!. This year my senior year I am back on the mellophone section and I have a problem!. A person that played trumpet was transfered to mellophone and somehow got the only good horn at school!. So im stuck with a crappy one!. (dont know why) Well the problem is that she is stuck in the 3rd trumpet mode (which basically means she is stubborn because she makes mistakes and doesnt fix intonation herself, and seeing as im going on for music, i know that there is a problem because it sounds bad!. also she is used to doing it herself so when i let her know, she ignores me -_-) Currently i vamped up to using an adaptor and a french horn mouthpiece to make my tone match what is needed for our show (tempo never goes under 144) and she never fixes the intonation!. Anything i can do!? Www@QuestionHome@Com
