As bands require leadership from within as well as from without, section leaders are usually selected from among the members of each instrumental section (a "section" comprises all the band members who play the same musical instrument). The section leader is always an experienced band member and is usually selected by the band director (rather than elected or self-appointed) for his or her leadership skills and experience. The section leader is responsible for the minute-to-minute instruction of his or her section members, and reports to the drum majors and the band director. Many larger bands appoint more than one section leader per section, with each having a "head" section leader, whether formally or informally designated as such. College-level military bands may use the term "section sergeant" or "section officer" in place of "section leader."
