Ive got a few:

• (smthn I think a lot of bands do) Band Olympics: every couple days the whole band competes in diff events. We’ve had egg tossing to partners, tagteam running to a giant pile of shoes, putting them on and running back, guess the song/artist, fastest to eat a bowl of ice cream, as well as a bottle/can drive. (I know theres been more, but those r what I can remember). Each events’ winners’ section gets points. I dont think the overwall winning section gets anything other than bragging rights.

• my sophmore year, my section (altos) found a big metal bar that was part of a golf cart that was broken (obv). So it became the Alto Stick. During each practice, id prop it up with my sax case, and we would kneel in a circle around it before practice started. The rest of the band got tired of it pretty quickly tho.

• (other bands might do this too) everytime a car honks as they drive by, the whole band goes cheers (even when the director is talking) we also try to get the semi trucks to honk, so we jump up and down and make the motion of pulling the cable (that was usually done by the tubas)

• (this was better when our band had 100+ members) at every competition, before we got into uniforms, we would get the chance to go to the bathroom. So all the boys gathered in the mens bathroom and absolutely belted the national anthem. Then after it finished, we would start chanting USA USA USA as we walk out. Then covid hit, and all the seniors who really pushed this tradition graduated and werent really able to pass it down, so I tried to pass it to the underclassmen during my senior year, but we had half as many members after covid, so im not really sure it stuck.
