Why is it said that music has something to do with governing the country? It is because of the "ritual and music system".

The system of rites and music was formulated by the Duke of Zhou in the early days of the founding of the People's Republic of China. One of its purposes was to consolidate the hierarchical society, and secondly, to draw lessons from the demise of the Shang Dynasty, to oppose "lewd music" and to adopt measures of "saving music". The implementation of the ritual music system consolidated the social status of the slave owner class and promoted the development of music. However, it makes music a vassal of ceremony, and makes music a model music centered on ceremony, and gradually tends to be rigid. In order to carry out "rule", the ruling class has formulated a set of very complicated etiquette and music to match it. People of different occasions and identities not only have different manners but also use different music. Such as worshipping the gods, "playing the yellow bell, singing big Lu and dancing" Cloud Gate "; Sacrifice to the ground shows that "it is playing too many clusters, singing bells and dancing" Xianchi "". ("Zhou Li. Spring Palace") When the two gentlemen meet, use the elegant "King Wen" as an example; The princes gave banquets to entertain the envoys of other countries, and used Xiaoya's Luming Literature, Sidu, Huang Huang Zhe Hua, and (Zuo Zhuan Xiang Gong Four Years). Another example is that the Emperor used Ode to Ancestors, but the scholar-officials could not use it. There are also strict rules about the establishment of bands and song and dance teams. The rules of the band are: "Palace County", that is, arranged in four directions: east, west, north and south; "princes Xuan county", lined up on three sides; "Doctors judge counties", arranged on two sides; "Astor County", only arranged on one side. The rules of the song and dance team are: the emperor uses sixty-four people and ranks them in eight rows, which is called "Eight Shu"; The princes used thirty-six people and arranged them in six rows, which was called "Six Shu". QingDaFu with sixteen people, in four rows, called "four Shu"; There are four scholars in two rows, which are called "Ershu"; ("Zhou Li. Spring Palace" and notes); Wait a minute. In a word, all these regulations on rites and music are aimed at strengthening people's hierarchical concept and finally achieving the political purpose of consolidating their rule. It is self-evident that education on rites and music must be strengthened in order to successfully implement the system of rites and music. Therefore, the Zhou Dynasty established the first institution of rites and music in Chinese history-the Spring Palace.
