Five-character rhythmic poetry is a kind of rhythmic poetry, that is, a poem with five words and eight sentences that conforms to the norms of rhythmic poetry, and belongs to the category of modern poetry.
Rhythmic poems originated in the Southern Dynasties, and evolved from Shen Yue's new-style poems which emphasized rhythm and antithesis in Yongming of the Southern Qi Dynasty. They were basically stereotyped in Shen Quanqi and Song Zhiwen in the early Tang Dynasty and matured in the prosperous Tang Dynasty.
For the people in the Tang Dynasty, the five-character metrical poem is a new poetic style born out of the five-character ancient poems. It inherits the principle that the sentences in the Five Ancient Dynasties have definite characters and rhyme every other sentence, and draws lessons from the metrical and dual principles of parallel prose, which has developed in many aspects:
1. Eight sentences each;
2. The third sentence and the fourth sentence, the fifth sentence and the sixth sentence must be opposed;
3. The leveling must be arranged according to a specific format, with one couplet being correct and two couplets being sticky;
4. Only the rhyme can be tied, and the rhyme has a fixed position, that is, even sentences rhyme (the first sentence can be tied or not);
5. The rhythm form is strictly two double-tone steps plus one single-tone step, and the single-tone step can only appear in the middle or the end of the sentence, not at the beginning, and the level of two adjacent double-tone steps must be opposite.
according to the above rules, five-character metrical poems are divided into two types: flat and flat, and each type is divided into two types: regular and partial.
