The drummer positioned before the Jin drum at the west end of the Yi Gates (the "Rites" Gates, located in the wall between the Da Cheng Hall and the Central Courtyard) strikes the drum frame once before sounding a continuous roll of alternate heavy and light beats which build up to a crescendo and gradually fade until a final beat is struck on the drum's center. At this point, the musician positioned by the Yong bell (located at the east end of the Yi Gates) strikes the bell once to mark the end of the first movement.
Due to the bell's resonance, this single beat is clear and prolonged. The purpose of the drum and the bell is to stir up emotions of piety and reverence in the worshippers in admiration of Confucius.
