Were you ever in marching band? It can be a great time if you like music, and it is a great way to make friends
Yes. I played trumpet. We had a great band teacher. Marching bands have a lot of brass, woodwind and percussion instruments in them most of the time it seems. 
I was never part of marching band but knew a lot of kids who were, I always thought the drums were very cool
Most of them wear military style uniforms with the schools name or symbols, and they are hot if you're outside.
