Since the Tang and Song Dynasties, clappers have been used to control the rhythm of music, and music has been divided according to sentences, which is called "clapping music" for phrases.

The rhythm characteristics of the board

In the Tang and Song Dynasties, the auxiliary "beating" and "stopping to beat" evolved into the later "scattered board", "drum beat" and "hand beat", and evolved into the later "upper board". The "upper plate" of later generations is a rhythmic "clapper" that can be matched with other words. In the Ming and Qing Dynasties, it became the main form of music rhythm in China.

Adagio is the most commonly used plate type in Jingyun Drum, which runs through the whole aria. The rhythm of adagio is "one board and three eyes". That is, the rhythm of "board, head eye, middle eye, last eye, board, head eye, middle eye, last eye, board, head eye, middle eye, last eye". Recording with music score is 4/4 beats. The first beat of each bar is the board, the second beat is the head eye, the third beat is the middle eye, and the fourth beat is the last eye.
