Poetry is one of the oldest literary forms. The combination of original poetry with music and dance is an important feature of early poetry. Lu Chunqiu Ancient Music records the song and dance sacrificial activities of an ancient tribe named Ge: Ge's Joy Once upon a time, three people sang eight songs: one said "carrying people", one said "mysterious birds", three said "enjoying vegetation", four said "fighting for food", five said "respecting heaven" and six said. These eight Ques are probably the oldest set of music known now, and three people are singing with oxtails. There are songs and dances. This set of music embodies the original form of the trinity of ancient poetry, music and dance.

Labor determines the characteristics of primitive literature: the trinity of poetry, music and dance. Because labor voice, labor action and labor voice are all naturally formed in the process of labor and are inseparable from each other. Poetry, dance and music, which developed from these three, were also sung together at first according to a certain rhythm. For example, what was playing at that time was Ge's song "Ba Que" quoted in "Lu Chunqiu Ancient Music".

The trinity of poetry, music and dance represents the pursuit of spiritual realm by ancient literati. There is a saying in Preface to Mao's Ancient Poems: "Poets have aspirations, have aspirations in their hearts, and express their feelings in poetry, which is not enough, so they lament, lament, chant and know nothing about dancing." It can be seen that poetry, music and dance are all produced because of the need of emotional expression, and they complement each other and reach the highest level of emotional expression. However, in ancient times, this form was only a pastime and leisure for literati.
