A bit of background... My daughter is 14 and has been playing trumpet for 3 years... Now she is about to enroll in high school band and we were handed a sheet showing the time they will be working next year... In the summer it will be 8 hours a day 5 days a week, half of it marching the other 4 playing because it is too hot for them to be outside in the afternoon... I'm a bit concerned that playing for 4 hours could cause some permanent damage. At the moment I considering just telling her she can't be in band because it seems to me the band director is putting his desire to win trophies above the welfare of the kids. Even when I was in college we never played that long at one time... Am I missing something?
