The Eta Beta chapter of Kappa Kappa Psi and Zeta Omicron chapter of Tau Beta Sigma are the National Honorary Band Service Fraternity and Sorority at Virginia Tech. The Eta Beta chapter, installed in 1974, and Zeta Omicron chapter, installed in 1979, are instrumental in providing support to The Marching Virginians, the University Concert Bands and the Virginia Tech Department of Music.

The chapters assist in the coordination and execution of The Marching Virginians Band Camp with such projects as Move-In, the Rookie Picnic, and the many equipment moves and numerous setups and tear-downs over the course of the week that are essential for making Band Camp a first-class experience for auditioning students.

During the academic year, both chapters are deeply involved with many of the most visible events associated with The Marching Virginians including Band Parents Day, MV Band Day, Band-A-Rama, and Hokies for the Hungry. In addition, both groups provide ushering and stage management for Department of Music concerts and collate tens of thousands of pages of drill throughout the season!
