We actually have the same problem with our percussion section (unfortunately, we have no actual drum line--as a seperate group), none of the percussionists listen to the section leader/drum major who is a senior and knows what he is talking about. The section consists of freshmen who can barely read music and have no desire to be there. It sucks, I know... the upperclassmen and the 5 or so sophomores are the only people who have some level of decency (thank you 6 years of private lessons). Needless to say, he gets quite pissed sometimes. Behavior and such problems are usually solved by the throwing of a bass mallet (and we're talking at least 60mph--literally) across the band room at the offending person -in front of the BD- or in sectionals, he often throws chairs or music stands. Don't get me wrong, I know him personally, and feel his pain, but violence and fear are the only ways to get the section to listen.
