Poems have developed from independent paragraphs in the Book of Songs to nine songs with the same content. When the poems are truly formed in form, they are gradually improved in style, with the same sentence patterns and the same number of words.
During the Southern Dynasties, five words and four sentences and five words and eight sentences became the main forms of group poems, and the forms of group poems were standardized. In addition to paying attention to formal beauty, poets in this period made bold attempts in the musicality of group poems, and the embryonic form of modern poetry appeared initially. Group poems are commonly known as five words and seven rhythms, and ancient metrical poems use "five" and "seven" as the word standard.
brief introduction
During the pre-Qin and Han dynasties, the internal sentence patterns of a group of poems were not unified, and mixed words often appeared. The number of sentences in a group of poems is not standardized, either three or seven words, or seven or eight words. From the Six Dynasties to the Six Dynasties, the poetic style was gradually unified, and the Southern Dynasties gradually formed the style of five words and eight sentences and five words and four sentences.
After the "Yongming Style" came into being, the poet's exploration of the rhythmic beauty of poetry continued to deepen, and the poetry of Wei, Jin, Southern and Northern Dynasties gradually moved towards the development path of "modern poetry". In the Tang Dynasty, the trend of metrical poetry school became more and more serious. Du Fu not only promoted the formation of metrical poems, but also played an important role in the creation of the school of five-metrical poems. His "Five Poems Crossing the Mountain Pond of Princess Yiyang with Wei Chengqing" is a group of five-rhythmic poems in the early Tang Dynasty.
