Bayin or Eight Fold System

The Bayin [八音] “eight tone” classification system is used to classify musical instruments according to what materials they were made from. However, the Chou-Li [Rites of Chou] an anonymous treatise compiled from earlier sources in about the 2nd century BC, had the following order: metal, stone, clay, leather, silk, wood, gourd, and bamboo.

The same order was presented in the Tso Chuan [Commentary of Tso] attributed to Tso Chiu-Ming, probably compiled in the 4th century BC. The bayin system is correlated to the eight seasons and eight winds of Chinese culture, autumn and west, autumn-winter and north-west, summer and south, spring and east, winter-spring and north east, summer-autumn and south west winter and north, and spring-summer and south east, respectively.
