Open, closed, open
From Wikipedia, the free encyclopedia
Open, closed, open is a technique of playing snare drum rudiments, especially used during auditions.
Open, closed, open technique consists of beginning the rudiment very slow and controlled, speeding up evenly until the maximum speed for the drummer has been reached, then slowing back down after maintaining that speed for approximately 5-10 seconds. Optimally, the drummer should end on the same hand as started, in case of alternating rudiments such as paradiddles. Also, the speed ended at should be approximately the same speed as the drummer began. It is also possible to use a Open, Closed, Stop technique to reach the desired effect. The Open, Closed, Stop technique offers a much more dramatic ending sound.
