No matter what form of metrical poems are: quatrains, eight-sentence metrical poems, long-sentence metrical poems and so on. There are two rhyming ways: according to whether the first sentence is flat or flat, it can be divided into rhyming and non-rhyming.
1, the first sentence is flat rhyme: the last word of the first sentence refers to the end of a flat tone, and this word enters rhyme.
Such as: frost, jade, bone, clean and beautiful, wrapped in the dazzling shadow in front of the heart. The fragrance was blown away by the wind and floated outside the threshold, full of feelings. -(a "Chanting Chrysanthemum") This is the rhyme of waiting for the harvest.
The so-called ping qi, that is, the second word of the sentence is ping sheng. The first word is flexibility, not counting.
Another example is: the warm orchid shakes the flower season, and Junshan embraces the emerald to drive the spring back. A thousand tears, a thousand memories, a little infatuation and an inch of dust.
The cloud dream has been written in the wind, and the Dongting is still snowy. I want to go to Xiaoxiang, and I want to marry a butterfly. -(Some "Jiangnan Spring") This is the rhyme of flat income. The so-called contraction means that the second word of the sentence is contracted.
2. The first sentence doesn't rhyme: it means that the last word in the first sentence is snoring.
Such as: lingering in the opportunity of meeting three stones, sighing the clouds in the world. The drums and horns are silent, and the milky way wants to turn to Cangshan.
It's hard to say how much the world of mortals knows. Purple Que never returns. Drink the breeze, push the pen and sing the rain omen. -(A Road to the World 15) This is an impartial style.
Another example: green grass, faint lead, red daughter. Wen Peng is thriving in Tingzhu, and does not envy the word Penglai. -(some "mixed feelings") This is a rhyme.
Rhyme requirements of poetry:
1, rhyme: at the end of every even sentence. That is, "rhyme foot" (mentioned in the three orders).
2. Question of the first sentence: The "rhyme mode" mentioned earlier, the first sentence does not rhyme, but the level tone rhymes.
Usually, the first sentence of five-character people does not rhyme, and the first sentence of seven-character people does not rhyme. Whether the first sentence is rhymed or not is often related to whether the first couplet is antithetical. If the first couplet is a antithesis, then the first sentence will be closed and not rhyme. If the first couplet is not a antithesis, the first sentence will be flat and rhyming.
If the first couplet is neither antithetical nor rhyming, it is not impossible, but the effect is not good and it looks stupid, especially the four-line.
3. Pingyi rhyme: Metric poems generally only use Pingyi rhyme. There are few rhymes, which belong to the non-standard category.
4, a rhyme to the end: metrical poems are not allowed to change rhyme in the middle, and rhyme feet can only be the same group of words. Except for the rhyme of the first sentence, the words in the adjacent rhyme can't be used for other rhymes, otherwise it is "rhyme", and rhyming poems can't be counted as standard metrical poems.
