The metrical poems in Tang Dynasty can be divided into metrical poems and quatrains. The rhythm is rigorous, and there are definite sentences (eight sentences per sentence), definite characters (five or seven words), definite sounds (flat and parallel) and definite pairs (two couplets in the middle).

The most obvious difference between quatrains and metrical poems is the different number of sentences. Each quatrain usually has five words and seven words, referred to as five quatrains and seven quatrains for short. The antithesis of quatrains is not as strict as that of ordinary poems.

The quatrains before the Tang Dynasty are called archaic quatrains, which have a flat rhyme and are relatively free to fight. The quatrains after the Tang dynasty are called near-body quatrains, and most of them don't pay attention to fighting, which is called prose. How does "Hometown Lianshu" say: "Teenagers leave home, old people return, and the local accent remains unchanged. When children meet and don't know each other, they smile and ask where the guests are from. "

Some quatrains are like half of a metrical poem, and the meter is the same as the first four sentences, the last four sentences or the middle four sentences of a metrical poem. It is the same as the first four sentences of the rhyme, and the last two sentences are opposite, such as Meng Haoran's "Sleeping in Jiande": "My boat is advancing in the fog, the day is getting shorter, and old memories begin. The vastness of the wilderness is deeper than trees, and the moon is very close to the moon.

The first two sentences are opposite to the last four, such as Wang Zhihuan's "Climbing the Crane Tower": "The mountains cover the daytime, and the ocean drains the golden river. But as long as you go up a flight of stairs, you can broaden your horizons by 300 miles. " They are four sentences in the rhyme, and the two sentences are opposite, such as Du Fu's quatrains: "Two yellow-green willows and a row of egrets go up to the sky. My window framed the snow-covered western hills. My door often says "goodbye" to ships sailing eastward.

Introduction to metrical poetry

Metric poetry belongs to modern poetry, which originated from Shen Yue and other new-style poems that paid attention to rhythm and antithesis during the reign of Qi Yongming in the Southern Dynasties. It further developed and became stereotyped in the early Tang Dynasty and prevailed in the Tang and Song Dynasties. Rhyme has strict rules in word, rhyme, even tone and antithesis. Its common types are five-character poems and seven-character poems.

Summary:

Regular poems are generally eight sentences each, and eight sentences are used to complete the whole poem. Every two sentences are connected into a couplet, which counts as four sentences. The first link is the head link, the second link is the collar link, the third link is the neck link and the fourth link is the tail link. The first sentence of each couplet is called antithesis, and the next sentence is called antithesis. The relationship between the first antithesis and the last antithesis is called adjacent sentence.
