One USC marching band tradition that occurs basketball games is that the band will start to scream 57 when the score reaches that number.  Additionally they will taunt any player on the opposing team who has a 22 as the number on their jersey jeering “tweeeenneey twoooo, tweeennneey twoooo”

The informant explained to me that this is a tradition that plays a role in inducting new members into the band.  New members learn this tradition at the first basketball game of the season when the rest of the band starts jeering and screaming they join in.

This is a good example of a tradition based around the liminal period.  The new members are in a place where they are physically in the band, in that they are preforming with them, but they don’t yet know the traditions, so they are not yet psychologically a member of the band.  After the first game however they learn the unofficial rules of being in band and leave the game feeling more a part of the band community.
