Wooden percussion instrument used in Buddhist rituals in China
A wooden fish, also known as a Chinese temple block, wooden bell, or muyu, is a type of woodblock that originated from China that is used as a percussion instrument by monks and lay people in the Mahayana tradition of Buddhism.[1][2][3][4] They are used in Buddhist ceremonies in China, Korea, Japan, Vietnam and other Asian countries. They may be referred to as a Chinese block, Korean block or, rarely, as a skull.[5]
Wooden fish often used in rituals usually involving the recitation of sutras, mantras, or other Buddhist texts. In Chan Buddhism, the wooden fish serve to maintain rhythm during chanting. In Pure Land Buddhism, they are used when chanting the name of Amitabha.
Wooden fish come in many sizes and shapes, ranging from 150 millimetres (5.9 in), for laity use or sole daily practice, or to 1.2 metres (3.9 ft) for usage in temples. Wooden fish are often (in Chinese temples) placed on the left of the altar, alongside a bell bowl, its metal percussion counterpart. Wooden fish often rest on a small embroidered cushion to prevent unpleasant knocking sounds caused from the fish lying on the surface of a hard table or ground, as well as to avoid damage to the instrument.
