"Music Notes" also said: Shang and Qi are two ancient songs with different origins and different contents, which have different effects on people's personalities. How can a character that is both brave and righteous be guaranteed to be formed without the appeal of poetry? Decisiveness, bravery, righteousness, and humility are all human character traits, and music has an influence on these character traits. The Musical Notes holds that this view that music can cultivate and influence the character of Heat is valuable.

The music also believes that musical performances should suit one's own personality characteristics, and each person should choose songs according to their own virtues. People who are generous, calm, soft and upright are suitable for singing "Ode"; People with a generous heart, straightforward and honest character are suitable for singing "Daya"; People with a frugal and courteous personality are suitable for singing "Xiaoya", and people with an upright and calm, honest and humble character are suitable for singing "Wind"; A person of frank and loving character is suitable for singing "Shang"; People with a gentle and decisive character are suitable for singing "Qi???.?". `

The "Music Record" proposes that people with six personalities are suitable for singing six kinds of poems, "Song", "Daya", "Xiaoya", "Wind", "Shang", and "Qi", which are consistent with the poems of the same name in the "Book of Songs". The author of "Music Notes" had already discovered the relationship between character and music 2,000 years ago, and put forward the idea of what kind of character people should sing what songs, which is commendable. Confucius recognized the power of music to move people deeply, but did not elaborate on it in more detail. Mencius and Xunzi exerted this thought, and Xunzi's exposition was more detailed. The "Music Notes" greatly exerts this viewpoint, and discusses the influence of music on people's emotions, personalities, wills and other psychology in a more in-depth and comprehensive manner.

"Music Notes" believes that music is the reflection of people's feelings on external things, and the thoughts and feelings expressed by music are closely related to the social and political conditions in which people live. The music of the ruling world is peaceful and happy, indicating that politics is peaceful and harmonious; The music of the troubled times is sad and angry, indicating that the politics of the time are **** and uncoordinated; The sad and sad music of the dying country shows the political danger and the hardship of the people at that time. Music and the politics of the time were interconnected. Music can reflect the rise and fall of a country's social and political customs.

A certain amount of music reflects a certain world. There will be some kind of music. This world includes certain socio-political, economic conditions and people's living conditions. "Music Notes" also hoped that the rulers of the time would care about music, on the one hand, through optimistic customs and knowledge of the rise and fall, as a means of investigating current affairs; On the other hand, it can also prevent and prohibit the sound of troubled times and the sound of the country, so that there is no chaos among the people, the princes are submitted, the military revolution is not used, the punishment is not used, the people have nothing to worry about, and the Son of Heaven has nothing to dissatisfaction with. From the perspective of the coordination of ritual and music, and the equal emphasis on ritual and music, the book discusses the special role of music in assisting politics and maintaining social stability.

We know that etiquette is about hierarchy and the norms of moral behavior, which must come from external coercion and constraint on people. Music is a melodic harmony produced by the combination of different scales of high and low, strong and weak, and long and short. The "Music Notes" emphasizes that the nature of this harmony reflects the perfection and rationality of the hierarchy, and attempts to show the harmonious order between the various classes that abide by their own rules, do not violate each other, and are orderly from top to bottom. It is hoped that under the influence of music, people will accept the moral and ethical norms prescribed by the ceremony, so as to harmonize people's ethics and psychology.

"Music Notes" believes that ritual and music complement each other and complement each other. They are one emphasizing the same, the other emphasizing the difference, there is the same will be a blind date, there is a difference will be respected. The noblest happiness is like the harmony of heaven, and the most solemn ceremony is like the difference between heaven and earth. Because of harmony, everything has its place; Because of the difference, it is necessary to sacrifice to heaven and earth. Music emphasizes harmony and unity, and etiquette emphasizes distinction and difference; The doctrine of etiquette and music runs through all human feelings.

It is precisely because of the different roles of ritual and music that they have different influences on political ethics. The system of etiquette was established, and the rank of the noble and the low was differentiated; When the literary style of music is harmonized, the relationship between the upper and lower levels can be harmonious. Happiness comes from the heart, and etiquette is expressed from the outside. Because happiness comes from the heart, it is honest and unpretentious; Because the etiquette is expressed from the outside, the quality of the culture is polite. The highest level of music must be gentle, and the most solemn ceremony must be simple. When happiness penetrates into the hearts of the people, resentment will be eliminated; When the rites are carried out, strife is eliminated.

Music focuses on the treatment of the heart, with emotional people, with morality, subtly make people listen to harmony. Etiquette, on the other hand, focuses on regulating people from the outside and forcing them to obey them. Joy from the inside, etiquette from the outside; Happiness from emotion, etiquette from reason; Happiness subtly infects people; Etiquette follows the system norms to enforce people. The cooperation of etiquette and music makes people have no complaints inside and no quarrel outside, so that the society presents a so-called peaceful scene of internal harmony and external harmony of the rule of etiquette and music.

In short, ritual and music each have their own essence, points and functions, and at the same time, they are interconnected, inseparable, and cannot be abandoned. Too much emphasis on pleasure will make people dissolute, and too much emphasis on etiquette will make people detached from each other. If happiness exceeds its limit, it will invite chaos; If there is no moderation, there will be evil. Therefore, etiquette and music complement each other, interact for use, and cannot be separated, and are an important means for Confucian self-cultivation, family harmony, governing the country, and leveling the world.
