Who points out the different functions of poetry, ceremony and music?

Poetry is used to express the will, to promote the individual's consciousness of seeking kindness and benevolence, to realize people's self-reliance by courtesy, and finally to cultivate the highest personality under the influence of music education.

in Confucius' view, a person's complete personality is first of all the function of poetry, ceremony and music. The so-called "thriving on poetry, standing on ceremony and becoming happy". Poetry, rites and music are the core of rites and music education in the Zhou Dynasty, which is formed by various rituals and their musical structures.

Prosperity, establishment and success are the overall meanings of rites and music, and also the overall meanings of Confucius' thoughts on music education. Grasping the perspective of music will make the confused cognition gradually clear, which is of course based on the premise of understanding the spatial and temporal characteristics of music, which is the truth expressed by Confucius.

from the theory of the relationship between the three, we need to learn from them by constantly advancing to form a whole. From the initial study of the poems of music, and then the study of etiquette, the poems of music and the ceremony of ceremony are finally integrated into a whole form by music. In the integration of music and ceremony, students perceive and appreciate the ritual demands of six sacrifices (so-called heaven, earth, mountains and rivers, looking around, taking the exam first), experience group harmony, and achieve an unbounded ritual effect. No individual can bear the whole connotation of the group and ritual of this ritual form alone.
