"Three Kingdoms·Wu Zhi·Biography of Zhou Yu": "Yu Shaojing is devoted to music. Although he is a descendant of the Three Lords, he has some shortcomings. Yu must know it and take care of it if he knows it." "Pinghua of the Former Han Dynasty" Volume 2: "When the emperor arrived at Jimen, the left-wing general Xu Mai greeted him with music and sent the emperor to Baling Bridge." Wen Chengxun's poem "Moving Music": "Really, music is the language of people's emotions."

Historical development:

It is impossible to examine exactly when music began to exist in human society. But as early as before humans developed language, they already knew how to use the strength of sounds to express their thoughts and feelings.

With the development of human labor, chants to unify the rhythm of labor and shouts to convey information to each other gradually emerged. This is the most primitive prototype of music: when people celebrate their harvest and share the fruits of their labor, People often knock stone and wooden tools to express joy and happiness.

There are differences between ancient music and music. "Book of Rites and Music": "All sound originates from the human heart. The movement of the human heart is caused by things. It is moved by the things, so it is shaped by the sound. The sound corresponds to it, so it changes and becomes square. It is called the sound. Compare the sound and enjoy it, and it is called music. Later called "music", it refers to an art that uses organized music to express people's thoughts and feelings and reflect social life.
