In the Tang dynasty, there was a major turning point, and the language of poetry changed greatly, that is, the colloquialism and popularization of poetry were greatly improved. "The foot of my bed shines with such bright light", "When those red berries come in spring" and "I wake up happily in this spring morning" ... because they are catchy and easy to remember and remember, they are easy to spread word by word. This is the first important reason for the widespread and enduring Tang poetry.
The reason why Tang poetry is widely spread is also because of metrical poetry. Although Shen Yue put forward the theory of "four tones and eight diseases" before the Tang Dynasty, it was not mature. Poetry entered the metrical style in the Tang Dynasty, and a large number of metrical poems appeared, such as seven-character metrical poems, five-character metrical poems, seven-character quatrains and five-character quatrains. One of the advantages of using metrical flat tone is that it greatly increases the sense of rhythm and musicality of poetry, which is convenient for memory and circulation. Sometimes, according to the rules of leveling, the last sentence or the next sentence can be easily and quickly remembered.
The third important reason why Tang poetry is widely circulated is that it is short and pithy, that is, most poems are short and pithy. Before the Tang Dynasty, no matter the Book of Songs, Songs of the Chu, or the poems of Wei, Jin, Southern and Northern Dynasties, most of them had a certain length. Like Cao Zhi's short "Seven Steps Poetry", there are not a few. In the Tang dynasty, the five elements, seven lines, five elements and seven lines emerged in large numbers and were very popular. These poems are 20 words short and 56 words long. They are easy to recite, and many of them are unforgettable. You can remember them as soon as you listen.
Formal style
There are various forms of Tang poetry. There are mainly five-character poems and seven-character poems in Tang Dynasty. There are also two kinds of modern poems, one is called quatrains, and the other is called metrical poems. Quatrains and metrical poems are five words and seven words respectively. Therefore, there are basically six basic forms of Tang poetry: five-character archaic poetry, seven-character archaic poetry, five-character quatrains, seven-character quatrains, five-character rhythmic poems and seven-character rhythmic poems. Classical poetry has a wide range of requirements for rhyme and meter: in a poem, the number of sentences can be more or less, the chapters can be long or short, and the rhyme can be changed.
Modern poetry has strict requirements on rhyme and meter: the number of sentences in a poem is limited, that is, four-line quatrains and eight-line meter poems. The words used in each poem have certain rules, and the rhyme cannot be changed; Rhyme also requires that the middle four sentences become antithesis. The style of ancient poetry is handed down from the previous generation, so it is also called ancient style. Modern poetry has strict rules, so some people call it metrical poetry.
