The director provides general guidance, selects the repertoire, interprets commentary and evaluations from judges, and auditions or recruits prospective members. What content is not provided by the director may be contracted from arrangers (who compose original works or adapt existing works) and copyists (who reproduce parts of the score), choreographers, and drill designers (primarily for field bands). With the assistance of section instructors, the director also teaches performance techniques—musical, martial, and visual—and assesses the pool of talent, choosing leaders and soloists as needed. The director also selects venues for public performance and oversees the staff that help provide funding and equipment. Many opportunities for member improvement are present: the director may organize clinics with various professionals, send representatives to specialty schools or camps, or plan trips abroad for education or exhibition.
