Kappa Kappa Psi and Tau Beta Sigma are the national honorary band fraterntiy and sorority. Both groups are dedicated to helping the university bands. They provide equipment setups, ushering, logistical support, and service to both the department and the community. Because of ONU's small size, the bonds that form between the students are stronger. In many of the instrumental groups, sections are very close and a positive spirit exists within them.
Student sections help provide the cohesiveness that keep the instrumental ensembles together.
