From Yu Shu-Shundian
The emperor said, "Hey! I command you to learn music and teach your son to be straight and warm, broad and chestnut, firm but not humiliating, simple but not proud. Poetry expresses ambition, song always speaks, voice always follows, law and harmony. Eight-tone harmony, no phase, harmony between man and nature. 」
Wei Xiao said, "Yu! Give a stone a slap in the face and all animals will dance. 」
Shun Di said, "Hey! Appoint you as the host of music and teach young people to be honest and gentle, broad and firm, resolute but not rude, simple but not arrogant. It is the expression of thoughts and feelings, the song is the language of singing, the five tones are formulated according to the content of singing, and the six tones are harmonious. If the sounds of eight musical instruments can be reconciled without disorder, then God and man will be in harmony. "
Wei Xiao said, "Ah! I am willing to beat the stone chime and let people who play with all kinds of animals dance to the music. "
