Four elements of metrical poetry:
First, rhyme: the second, fourth, sixth and eighth sentences of metrical poetry must rhyme, that is, the last word of even-numbered sentences must rhyme. The first sentence can be bet or not. The five laws take the first sentence as a positive example and the rhyme as a variant; The seven laws take the rhyme of the first sentence as a positive example, and the non-rhyme as a variant.
level tone: when writing metrical poems, we should master how the four tones of Chinese can be divided into two categories: level tone (equivalent to the level tone and the level tone of modern Chinese) and level tone, and level tone is the rising tone and falling tone of modern Chinese, plus the entering tone of ancient Chinese.
3. Sticking to pairs: Rhyme is to combine the four flat sentence patterns mentioned in the previous section according to the principle of sticking to pairs to form a verse style. The so-called "sticking" means, in short, that the second word of the post-linked sentence is flat and parallel, and it must be consistent with the flat and parallel of the second word of the pre-linked sentence, so as to stick the two sentences together.
fourth, antithesis: both the second couplet (jaw couplet) and the third couplet (neck couplet) of metrical poems must be antithetical.
the first is that the upper and lower lines must be opposite.
Secondly, the sentence patterns of relative sentences should be the same, and the syntactic structures should be consistent, such as subject-predicate structure versus subject-predicate structure, partial structure versus partial structure, and predicate-complement structure versus predicate-complement structure.
Extended data:
In a couplet, the total number of flat-voiced words and flat-voiced words is equal. If "135", which can be handled flexibly, should use the flat-voiced word instead of the flat-voiced word (or should use the flat-voiced word instead of the flat-voiced word), then it is often necessary to change the flat-voiced word into the flat-voiced word (or change the flat-voiced word into the flat-voiced word) at the appropriate place in this sentence or dialogue, so as to keep the number of flat-voiced words in a couplet. In other words, the first use of the argument (illegal), and then save it, together is called difficult to save.
for example, the five-character sentence of "flat and flat" is flat and even. The third word of this sentence can be ignored, and it can also be used in a flat voice. But if the first word is changed to sound, it will become: flat and flat. Apart from rhyme, there is only one flat sound in the whole sentence, which is called "solitude", which is a taboo in modern poetry and is rarely seen in Tang poetry. In Du Fu's poem "Two Bows Hanging from the Arms", a sentence that is lonely and irregular like this is called an awkward sentence.
