The University of Arizona

About Us


The University of Arizona Drumline is the battery-only percussion section for the “Pride of Arizona” marching band. As of around 1986 the line has been a drum corps style unit. The UA Drumline is also an individual performance ensemble, and as a University function provides outreach to the community through workshops and performances.


One of our strongest goals as an ensemble is to create experiences that are enjoyable to the performer as well as the listener. We believe in educational and personal growth while teaching rhythmic accuracy, precision, and consistency. We provide equal opportunity on the various instruments, and embrace quality over quantity. We strive to maintain our excellence and precision as one of the top collegiate drumlines in the country.


The University of Arizona Drumline exclusively plays Mapex drums. In addition, we are very fortunate to have obtained sponsorship from Zildjian cymbal company, Remo Inc., and Vic Firth drum sticks, providing top-of-the-line equipment in support of our efforts.
