Do poems need rhyme?

The so-called rhyming (also called rhyming and Ye Yun) means putting the words with the same rhyme in the designated position. The so-called rhyme is to classify words with the same vowels into one category, which is called rhyme. All the words in the homonym are homophones. Any poem requires rhyme, no matter ancient or modern, Chinese or foreign. The difference is that there are more or less restrictions on rhyme, and there are strict and wide restrictions. This is also the biggest difference between poetry and other literary genres. 108 Pingshui rhyme ② is commonly used. Rhyme is an important means to enhance the musicality of poetry. Modern poetry pays great attention to rhyme in order to make the tone harmonious and easy to remember. The ancients usually used official books that specially instructed the use of rhyme, such as Tang Yun, Guang Yun, Libu Rhyme, Peiwenyun, Integration of Rhyme and Combination of Rhyme. Among them, the rhyme of "Xin Kan" in Wang Wenyu in the Southern Song Dynasty is the most popular, that is, the so-called 108 level rhyme. But what needs to be understood is that it is not worth destroying the essence of poetry in order to accommodate rhyme. Unless you take part in the imperial examination, even if a sentence or two rhymes occasionally, the ancients are allowed. There are strict rules on the rhyme of regular modern poetry, which can be summarized as follows: the first sentence can be put or taken off, and the next sentence must be flat rhyme 3 1. Even sentences rhyme: rhyme is 2468 sentences, quatrains rhyme 24 sentences, and the first sentence may or may not rhyme. For example, to judge Han Zuo (Du Mu) in Yangzhou. There is water in the green hills, and the vegetation in the south of the Yangtze River is withered in autumn. Where does the Jade Man teach oral sex at Bridge 24 on a moonlit night? The first 124 sentence rhymes. Another example: Leyou Tomb (Li Shangyin), with a twilight shadow in my heart, I have opened it in Leyou Tomb. Sunset, infinitely beautiful, only near dusk. The first sentence doesn't rhyme, but two or four sentences rhyme. Generally speaking, it is common that the first sentence of five-character poems does not rhyme, and it is also common that the first sentence of seven-character poems rhymes. Please refer to the rule of leveling whether the first sentence rhymes. ④ 2. Only flat lines are allowed: modern poetry stipulates that only flat lines are allowed, which is almost a dead rule. In fact, in the style of modern poetry, it would be awkward to bet on a flat brick, so the ancients could consciously abide by this rule. There are no counterexamples in memory, so I won't give them here. 3, a rhyme to the end, the middle can not change rhyme. Ancient poetry (ancient style) is allowed to change rhyme halfway, but modern poetry is not allowed. The rhyme of the first sentence can be borrowed from the rhyme of ancient poems with neighboring rhymes. The rhymes of neighboring rhymes, such as Dong Yi and Erdong, four senses and five flavors, can be mixed and used together, which is called Yun Tong. The rhyme of modern poetry must strictly use only the words with the same rhyme. Even if there are few words in this rhyme (called narrow rhyme), it can't be mixed with words in other rhymes, otherwise it is called rhyme, which is a big taboo of modern poetry. But if the first sentence rhymes, you can borrow adjacent rhymes. Because the first sentence can be put or not, you can bend the rules. Such as "Drunk Drinking in the Army to Send Ba Shen Liu Sou": The wine is thirsty for Qingjiang River, and the rest is dry to soothe the dusk. Soft sand leans on the seat, and Leng Shi wakes up drunk. Picnics are accompanied by accounts, and Huayin is happy. Several cups are missing. They have all been sent to Shen Ming. This song "Ting Xing Ling Ming" consists of nine tones, but the first sentence borrows the word "Qing" from Ba Geng. This is called borrowing neighboring rhymes, which was popular in the late Tang Dynasty and even formed an atmosphere in the Song Dynasty. Please refer to Tongzhuan Guyun and 108 Pingshui Yun.
