What are the classifications of ancient poetry according to time?

China's ancient poems can be roughly divided into three categories according to the content: poems, narrative poems, lyric poems and philosophical poems, and can be divided into ancient poems, modern poems and free verse (modern poems) according to the form.

According to time, it should be Tang poetry and Song poetry.

1, ancient poetry (or "ancient style"), whose name began in the Tang Dynasty. In the Tang Dynasty, neo-metrical poems were called modern poems, while poems with less metrical restrictions before the Tang Dynasty were called ancient poems, including The Book of Songs, Yuefu poems and folk songs in the Southern and Northern Dynasties. Later generations followed the theory of the Tang Dynasty and imitated the folk songs of Yuefu before the Tang Dynasty, the poems and literati after the Tang Dynasty. There are four words (such as The Book of Songs), five words (such as Han Yuefu's poems), seven words (such as Cao Pi's trip, Bai Xuege's Farewell to Tian Li Wu's Home), miscellaneous words (such as Li Bai's Shu Dao Nan) and so on. The rhyme of ancient poetry is relatively free.

2. Metric poetry is a poetic style formed in the Tang Dynasty, also known as modern poetry. There are uniform and strict regulations on its level tone, rhyme, rhythm, structure, number of words and pause. There are two kinds of quatrains and metrical poems, each with four quatrains, and the last word of one or two sentences or four sentences must rhyme (the last word of the third sentence is optional). According to the number of words in each sentence, it can be divided into five-character quatrains and seven-character quatrains. The last words of the first two or four sentences in autumn poems are "Liao, Chao and Xiao". Generally speaking, a metrical poem has eight sentences, and more than eight sentences are called "long rhythm". Generally, each metrical poem consists of four lines and eight sentences, two of which are a couplet, which is divided into head, chin, neck and tail, in which the couplet and neck are up and down. The couplet "Leaves fall like waterfalls, but I think the long river always rolls forward" forms a neat antithesis, and the last sentence of 12468 rhymes with "Ai" (in ancient times, Huihe Cup also rhymed with "Ai").

3. Ci is a poetic art form that rose in the late Tang Dynasty and flourished in the Song Dynasty. Tunes have fixed frames, sentences have fixed numbers, and words have fixed tones. It's also called inflectional words, long and short sentences, redundant poems and musical interest. This is a poem that delights in music. Poetry and words belong to the category of verse, but poetry is only used for chanting, and words are sung in music. Every word has a melody that expresses musicality (that is, words). The number of words and the length of sentences are fixed and have a certain format. The rhyme is strict and the words are even. The sentence patterns are uneven and the sentences are of different lengths. Song Ci can be divided into two types in style: the bold school is represented by Su Shi, Lu You, Yue Fei and Xin Qiji, and the graceful school is represented by Liu Yong, Zhou Bangyan, Yan Shu, Qin Guan and Li Qingzhao.

4. Qu is an artistic form of poetry that rose after Tang poetry and Song poetry, and flourished in Yuan Dynasty. It is composed of zaju and Sanqu, and it is the main body of literature in Yuan Dynasty. Zaju is a kind of drama, which generally consists of 40% drama and a wedge, and 10% is equivalent to a scene of modern drama. Wedge is equivalent to prologue or cut, which is placed at the beginning or middle of the whole play. Sanqu is a kind of lyrics that combines long and short sentences with music. The rise of Sanqu and the decline of Ci are almost simultaneous. It includes poems and collections, so it is called "Sanqu", which is relative to the whole drama of Yuan Zaju. At the same time, Sanqu is similar in style and relatively free compared with characters, which can be fixed in characters with interlining and can be used in spoken language.

"divertimento", also known as "divertimento" and "Sandivertimento", usually consists of several tunes in the same palace tune. The tune is based on the long and short notes of the music. Regardless of Sanqu or Opera, the names of Gongdiao and Qupai are generally indicated in front of it, and each Qupai belongs to a certain Gongdiao, such as [Yuediao] Tianjingsha Qiu Si [Yuediao].
