"1" and "even tone" are the tones of words used in Chinese poetry. Flat means straight, it means twists and turns. According to the rhyme books revised from Sui Dynasty to Song Dynasty, such as Qieyun and Guang Yun, there are five tones in Middle Chinese, which are called Ping (,Yangping), Shang, Qu and Rusheng. Except for the flat tone, the other three tones have high and low changes, so they are collectively called Legato. There is a certain format in the use of flat and even words in poetry, which is called meter. Pingsheng and Silence refer to the poetic rhythm composed of Pingsheng. Flat tone is an attempt to dualize the four tones. Four tones are four tones in ancient Chinese. Tone refers to the level, fluctuation and length of sound. On the basis of four tones, the flat tone is summarized through incomplete induction. Flat refers to straight, flat refers to twists and turns. In ancient times, it was raised, lowered, lowered, and the rest was flat. Since Zhou Deqing in Yuan Dynasty, Yin and Yang have been divided equally and returned. Gradually form a pattern of flat tone, flat tone, rising tone, falling tone and canceling entering tone.
2. Rhyme, or rhyming, refers to the use of words with the same or similar vowels in the last word of some sentences when creating rhymes, so as to produce a sonorous sense of harmony when reading or singing. These places where the same vowel is used are called rhymes.
Second, expand the scope of knowledge:
1, short list of flat couple poems:
Five laws are equal: the first word and the second word of the first sentence are flat.
The five laws start from the beginning: the first word and the second word of the first sentence are silent.
Seven laws are equal: the second word of the first sentence must be flat.
Starting with the seven laws: the second word of the first sentence must be linked.
Couplet: (couplet) Up and down.
2, rhyming taboo:
(1), avoid heavy rhyme.
That is, the same rhyme word appears repeatedly in the rhyme of a poem, which is a big taboo.
(2) Avoid synonyms.
For example, a poem uses "flower", "flower", "fragrance" and "fragrance" at the same time.
(3) Avoid rhyming
Most ancient poems were written according to the official rhyme, and many words that we thought were homophones were included in different rhymes in the official rhyme, such as "winter" and "east". If you are juxtaposed in the same poem, it is rhyming. This is mainly due to the change of ancient and modern pronunciation, so it is unnecessary to emphasize this point today.
