As we all know, the first collection of poems in history is called Poetry, which is also called The Book of Songs. There are 300 poems in The Book of Songs, which are widely and meaningfully sung by the people in each capital. At that time, no one had defined "Wen", only knowing ceremony and joy. Rites can't be abolished, and joy is generally the case. Naturally, the so-called poetry is joy, so there is Yuefu after 300 songs. Even after the Sui and Tang Dynasties, the quatrains of regular poems must rhyme, and people can sing them like singing. Therefore, poetry is an organic whole. As for the words, there is no need to explain too much. Generally speaking, words are songs, and all words are filled in according to songs, that is, for people to sing. China's traditional drama is a combination of lyrics, songs and stories. As the saying goes, poems and plays written by people who don't know music are not perfect, so it's a good idea to have both. Poetry is the subject of music and music is the rhythm of poetry.
