All band students are required to participate in two smaller performing ensembles. The ensembles are divided into two groups: "A" ensembles and "B" ensembles. Each student chooses an "A" and a "B" ensemble.
There is no guarantee that students will be the ensemble of their choice. Instrumentation, playing ability, and optimal ensemble size also determine ensemble assignments.
Some ensembles are by audition and/or invitation.
The year is divided into five zones. A new zone begins after major performances. Some ensemble choices change while others continue.
