I have no idea what grade our H.S. Band played. We have 4 different bands. (concert, symphonic, wind ensemble, and wind symphony) The wind symphony which my son was in last year plays music often performed by university bands. The director never talked about the Music level. I could probably dig up the name of some pieces. The lowest level band will take beginners although most students have played an instrument for a few years by that time. Band director places a student in by audition and every year a few freshman get into the top level band, but mostly the concert band is freshman/sophomores. And wind symphony mostly seniors.
