We're an Arts school, so in order to get into the band you have to audition, and you have to "reaudition" to stay in as well (though there has never been a time when my teacher has kicked anyone out because they failed the reaudition).
That's why I'm glad I play Third in the Clarinet section. I never have any solos (except one time, because everyone else who played this one part was absent. D|) and I mush blend with the band. :B
