Rhyme originated in the Southern and Northern Dynasties and matured in the early Tang Dynasty. Eight sentences, four rhymes or five rhymes. The two leagues in the middle must fight each other. The second, fourth, sixth and eighth sentences rhyme, and the first sentence can be played or not, usually in a flat voice. The third sentence, the fifth sentence and the seventh sentence do not rhyme, and the last word must be clear. It is divided into five words and seven languages, referred to as five laws and seven laws, and occasionally called six laws. Every song with at least ten sentences is called regular arrangement.
"-"stands for flat sound, and "|" stands for flat sound, which is subject to the medieval sound. At that time, there were four tones in Chinese characters: flat, up, down and inside, and up, down and inside were all flat tones. A circle added to the symbol means flat and graceful, and △ means rhyming words. Rhyme embodies the phonetic characteristics of flat and even Chinese characters. If Chinese characters are not flat, they have no rhyme.
The basic sentence pattern of the Seven Laws is "43", such as "On the side of the sinking boat-crossing Qian Fan, before the sick tree-Wan Muchun". Another common sentence pattern is "four two one", such as "falling trees-rustling-falling, endless Yangtze River-rolling-coming". Special sentence pattern "25", such as "Five Watches-Drum Horn More Tragic, Three Gorges Shadow-Galaxy Shake"; "May 2", such as "The sad voice in the corner at night-talking to himself, the moonlight in the sky is good-who will see it"
This is a rough introduction. Rhythm poetry has more than one form. Sometimes a poet does not conform to the norms and changes it, that is, it is uneven, which is called "awkward body". The so-called "depression" of predecessors, except sometimes changing the second, fourth and sixth words, focuses on the fifth word of seven words (the third word of five words). These two couplets are both called "awkward sentences", and the first sentence is called "awkward method". Where the word "save" is needed, it is not misused if it is saved. The word "save" should be used in the previous sentence, and the word "save" should be used in the next sentence to adjust the tone and make * * * harmonious, which is called "difficult to save". Some people don't want to save.
The antithesis is to express related or opposite meanings with sentences with equal words and similar syntax. Rhyme usually requires both, but sometimes it can be flexible.
