Definitely! Music is a form of creative expression. Some students are very talented, and band might help those students pursue a future career in the music industry. For others, it's a good way to meet friends and possibly start a garage band. :)
Bands and their booster clubs help present a solid front of support for the teams, students, school itself, neighborhood, and community. They develop pride. Who cannot watch the Rose Parade and not see the pride in those marching bands!
