Alumni Drum Corps are generally composed of individuals who were at one point members of the affiliated organization. In most cases, however, membership in the Alumni corps is open to anyone who wishes to join. They generally do not compete and have a much lighter performance schedule than their counterparts. Some Alumni corps no longer have an active Junior or Senior Corps counterpart due to the corps folding.
The shows performed by Alumni Corps tend to be in a traditional, historic style.
