Closed roll

A type of multiple bounce roll with typically three or more bounces per stroke. This roll is commonly used with a concert bands or orchestras. When performed as a rudimental drumming exercise, the roll would begin slow (or open) so one could count the individual bounces, then gradually increase in speed to one continuous sound ( close), then gradually decrease in speed to where the bounces were again distinguishable ( open).See also roll; press roll; open roll; multiple bounce roll.
