This is the exact reason my kids will NEVER do band.
I didn't understand when I was in middle school why my mother wouldn't let me go on, all she said was that she didn't want me to march. When I notified my band director, I went from first chair to last in a matter of weeks, I never won another challenge - I know I didn't suck that bad considering I held first chair for the last 2 years. My flute was also stolen for almost 2 weeks. I told the director I was quitting the next day if I didn't get it back. It was "left" in the same spot I always kept it the next day. Needless to say, our program didn't handle rejection well.
Flash forward a few years. I returned to the school I graduated from as a paraprofessional for 2 blind teens. Both of them marched. The boy played trumpet (limited vision, but enough to march) and the girl was on the drum line. As school progressed and her goals changed (she wanted desperately to break into the top 10 in her class) she found out that band was taking up too much time for her course load.
She talked to the instructor and he wrote a horrible letter to her counselor and the school principal saying that myself and her teachers were failing her because she didn't have time for band. Taking great offense to his comments, I responded by reminding him the academics ALWAYS come first and there is no way I would let my child (as in my child, not my student, her mother was of the same opinion I found out) be struggling academically and be allowed to continue in an EXTRAcurricular that required more time than a part-time job. He then tried guilting her into staying by telling her she was letting the WHOLE band down if she walked away (my student is very sensitive and doesn't like people being upset with her). She nearly had a breakdown due to the pressure. Ultimately she walked away and ended up graduating 3rd in her class - she missed Saluatorian by 0.028 of a point.
Over the last 2 years he's lost 25% of his band kids due to the unreasonable requirements for the class. I will say they do understand that kids have some commitments and require them to attend 4 of the 6 home games in order to pass. I think it's a little steep to require them to attend all of them. The band had to switch competitions circuits too due to lack of enrollment this year. They finished their last competition last week. The competitions were probably the worst requirement of all. Most of our kids would have to be at the school at 4 a.m. to load the bus and wouldn't return until 1-2 a.m. after the competition. Ridiculous!!!
So you are ready to condemn EVERY band program because you had ONE bad instructor? We have 3 full time band directors, one band director from another school (an hour away) that comes to work with our band, we have 4 college students studying to be band directors all work with our band every year and NONE of them are like this AT ALL. They are wonderful instructors that expect a lot out of the kids yet still make it so much fun that the kids can't WAIT for band to start each year.
Then she can't be surprised there was a conflict.
