Therefore, happiness is a thing that makes people happy. But the gentleman is happy to get benevolence and righteousness, and the villain is happy to satisfy his selfish desires. Restraining selfish desires with righteousness will result in happiness without confusion; If we only focus on our desires and forget righteousness, we will fall into confusion and will not find true happiness.

Therefore, as mentioned earlier, the gentleman should abandon the love of indulgence to reconcile his mind, promote music education to complete the education, and the implementation of music education will return the people to the way of benevolence and righteousness. The so-called virtue is the beginning of human nature. The so-called music is a flower that blooms from virtue. Jinshi, silk and bamboo is a musical instrument that expresses people's aspirations, while song is the sound of elongating the tone to express the mind, and dance is an action that expresses the mind with various gestures. Poetry, song, and dance all come from the heart and are accompanied by musical instruments.

Therefore, the heart expressed by the music is deep and distinctive, and the atmosphere is strong and imperceptible. The virtue of harmony is accumulated in the heart, and the essence of happiness can be expressed externally. What kind of virtue there is, what kind of happiness there is, only music is hypocritical.

Music is the expression of inner activity, sound is the expression of music, and literary rhythm is the modification of sound. The gentleman is moved from the heart to punish, loves its expression, and then pays attention to the rhythm of the style. For example, in the dance of "Dawu", the first step is to beat the drum to get everyone ready, and then take three steps to indicate that the dance is about to be made; After a song, start from the beginning, to indicate that the second time to send troops to destroy Shang. At the end of the dance, they return to their original positions neatly. The dancers are fast, but not wild; The expression is profound, but not subtle. The whole dance shows that only the warrior king can not forget benevolence and righteousness when he is happy, and completely practice benevolence and righteousness to benefit the world, not for selfish desires.

Therefore, people can not only see the matter of King Wu's war, but also the righteousness of King Wu's war. At the end of "Dawu", the moral status of King Wu is also clearly displayed. Watching "Dawu", the gentleman will increase his kindness more and more, and the villain will also use it to reflect on his mistakes. Therefore, happiness is the most important way to govern the people.

Joy is for people to listen to and watch, and only to give, not to reciprocate. Etiquette is about coming and going, both giving and repaying. Joy is the mood of joy that comes from the heart, and etiquette goes back to its starting point. Joy should show inner virtue, and etiquette should repay kindness and think of the source. The so-called chariot is the chariot of the Son of Heaven; The so-called dragon flag is the flag of the Son of Heaven; The tortoise shell with a blue-black rim is the treasure turtle of the Son of Heaven; Plus herds of cattle and sheep. All these things were given by the Son of Heaven as gifts to the princes who were about to leave the dynasty.

What music expresses is the immutability of feelings; What is expressed in the rites is the immutability of the truth. Music emphasizes harmony and unity, and etiquette emphasizes distinction and difference. The doctrine of etiquette and music runs through all human feelings. Exploring the origin of people's hearts and inferring the law of change is the essence of music; It is the principle of propriety to carry forward people's sincere character and remove those hypocrisy. Rites and music can conform to the affection of heaven and earth, reach the kindness of ghosts and gods, move the gods and gods to descend, transform and nurture the body of all things, and adjust the relationship between kings, ministers, and masters.

Therefore, when the saints carry out ritual music, the heavens and the earth will become brighter because of it. Heaven and earth merge happily, yin and yang sense each other, and all things are nurtured. So the vegetation is luxuriant, the crops sprout, the birds spread their wings and fly, the beasts are alive and jumping, the stinging insects wake up from hibernation, the birds hatch their eggs and brood, the beasts are conceived, the viviparous ones are not aborted, and the eggs are not broken. It all comes down to the function of music.

The so-called music does not refer to Huang Zhong Dalu, playing the piano and singing, raising the shield and dancing, these are just the subtleties of music, so it is enough to let the children's door perform. The so-called ceremony does not refer to laying down the feast, displaying wine and food, displaying ritual utensils, and going up and down the steps, going forward and retreating, etc., these are just the subtleties of the ceremony, so it is enough to let the clerk do it. The musician only knows the rhythm of the verses, so he can only play them facing north; Zong Zhuguang understands the etiquette in the temple, so he can only follow the corpse's ass to sponsor the etiquette; Shang Zhuguang knows funeral rites, so he can only follow behind his filial son to remind him of etiquette.

From this point of view, those who know the truth well should be above, and those who only know the skill should be below; Those who know the truth should be first, and those who only know the skills should be last. Because the first king understood this kind of truth, there is a top and a bottom, and there is a first and a last, so he can make music for the world.

Wei Wenhou asked Zixia: I put on my dress and hat, and I went to listen to music respectfully, lest I doze off. If you listen to the voice of Zheng and Wei, you will be tireless. What is the reason why the old music makes me feel that way, and how can I explain the new music that makes me feel this way? Zixia replied: Now let's talk about ancient music first, and when dancing, we advance and retreat together, and we are uniform; When singing, remove the peacefulness and be upright and broad. All kinds of orchestral instruments are waiting for the conductor of the accompanying drums, and when the orange drums are played, the music is played in unison. Drumming at the beginning of the performance and cymbals at the end of the performance. Use the phase to adjust the ending song, and use Ya to control the fast tempo. After the performance, the gentleman also has to make a discussion, using the past as a metaphor for the present, of course, it is nothing more than the principle of self-cultivation and Qi family governing the country and leveling the world. This is how ancient music is played.
