The Zeta Xi chapter of Tau Beta Sigma, the National Honorary Band Sorority, is an integral part of the band program here at San Diego State University, and is the local manifestation of a nationwide network of Sisters dedicated to the promotion and service of band music in the Nation's colleges and universities.

Our primary purpose is to serve the University Bands and to help develop leadership and enthusiasm among the band members. We help students to develop friendships and a deeper bond with other band members, both within SDSU and with other schools across the country. We also function as an honor society, recognizing outstanding band members through the privilege of membership.

Throughout the football season, we do a variety of things to help the Marching Aztecs, including: copying music, distributing uniforms, setting up and tearing down the field equipment, and planning fun activities for band members throughout the semester. For the Wind Symphony and Concert bands, we help with moving equipment, and often host receptions for the audience following performances.
