Metric poetry has strict requirements for rhyme. First of all, they are all flat and even rhymes, and there are a few flat and even rhymes, most of which are five-character poems, but metrical poems take flat and even rhymes as a positive example, and rhymes are traditionally classified as ancient poems; Secondly, no matter quatrains, metrical poems or verses, they must rhyme to the end and cannot be changed in the middle; Finally, both five-character poems and seven-character poems are required to rhyme, and the single sentence does not rhyme, but the first sentence may or may not rhyme. The first sentence of a seven-character poem rhymes more, while the first sentence of a five-character poem rhymes less.
There may be some mistakes in rhyme. The last word of every sentence you say is the same, called double rhyme. Common mistakes are:
1, rhyme, also known as rhyme, the rhyme of modern poetry requires that only one rhyme can be put in a poem, and all rhyming words must be in one rhyme department in Ping Yun Shui. It is not allowed to rhyme with words in other rhymes, that is, the rhyme of "falling rhyme" is limited to one rhyme part (rhyme can be used when the first sentence rhymes), otherwise it rhymes;
2, rhyme, that is, you choose this rhyming word, which is inconsistent and incoherent with other meanings of the whole sentence;
3, heavy rhyme, that is, what you said, it is impossible to repeat a word in a poem as rhyme;
4, inverted rhyme, which is also a common poetic disease, refers to the inversion of normal words for rhyme, such as deliberately writing the harp as a harp and writing the wind and rain as a wind and rain;
5. Dumb rhyme, "Dumb rhyme" is a word with unclear tone and meaning as rhyme;
6. Unused rhymes are uncommon words, so use them as little as possible;
7, compound rhyme, words with the same or similar meaning should not be repeated. For example, if you use the words "sorrow", "sorrow", "flower", "fragrance" and "fragrance", don't use another one;
8. Squeezing rhyme is also called "committing rhyme" or "taking rhyme". If there is a rhyme in your sentence, don't use it in your sentence, or you will make serious pronunciation mistakes. Let's take a poem as an example: where we meet, the grass is tender, and the cliffs are thousands of peaks. Where is his date? A pine tree on a cold stone. This poem uses the rhyme of Erdong, but the first sentence and the second sentence have two words "feng" and "feng", which are also in the rhyme of Erdong, and this is "squeezing". However, it should be noted that the word "Rong Rong" is a reduplication and does not belong to "squeezing rhyme".
The above are the basic requirements of rhyme in metrical poems, which I hope will be helpful to you.
