What are the artistic forms of Yuan Qu in Tang Poetry and Song Poetry? What are the reasons for the different artistic forms in different historical periods?

Tang poetry generally refers to poems written in the Tang Dynasty.

The Tang Dynasty is considered to be the dynasty with the richest old poems in China, so it is called Tang Poetry and Song Poetry. Most of the Tang poems are included in The Complete Poems of Tang Poetry. Since the Tang Dynasty, anthologies of Tang poetry have emerged continuously, and the most widely spread is "Three Hundred Tang Poems" compiled by retired scholars in Hengtang. The creation of Tang poetry can be divided into four stages according to time: early Tang, prosperous Tang, middle Tang and late Tang.

Song ci, ci and poetry.

Because it is the lyrics of music and harmony, it is also called tune, Yuefu, music movement, long and short sentences, poetry, piano music and so on. It began in the Tang Dynasty, took shape in the Five Dynasties and flourished in the Song Dynasty. Song Ci is a brilliant diamond in the crown of China's ancient literature, and a fragrant and gorgeous garden in Yuen Long, an ancient literature. With its colorful and varied charm, she is on a par with Tang poetry and Yuanqu, and has always been said to be the best companion of Tang poetry, representing the prosperity of a generation of literature. Later, there was a book with the same name, Song Ci.

Yuanqu, that is, "Yuan Zaju".

Yuanqu is a wonderful flower in the splendid cultural treasure house of the Chinese nation, which embodies its unique characteristics in ideological content and artistic achievements and has become three important milestones in the history of China literature.

The Yuan Dynasty was the heyday of Yuanqu. Generally speaking, Yuan Zaju and Sanqu are collectively called Yuanqu, and both of them use Beiqu as the singing form. Sanqu is the main body of literature in Yuan Dynasty. However, the achievements and influence of Yuan Zaju far exceeded that of Sanqu, so some people called it "Yuan Qu".

Although there is a fixed framework, it is not rigid. Interlaced characters are allowed in the fixed frame, and sentences can be added to some qupai. In terms of rhyme, it is allowed to be flat and even, which is more flexible than quatrains and Song poems in metrical poems. Therefore, readers can find that two songs with the same "Qupai" sometimes have different words, which is the reason (the one with the least words in the same Qupai is the standard frame). Yuanqu is also called Yu Jihe Yuefu.

There are five words, seven words, quatrains and metrical poems in Tang poetry. Tang poetry is mainly composed of five or seven words, and the words should be filled in according to the epigraph. Sentence patterns vary in length, so they are also called long and short sentences. Music is similar to words, so it should be filled in according to the music card. Therefore, the poems written by Tang people can be called poems, the words written by Song people and the songs written by Yuan people, which are called Ci and Qu. The epigraph of Song Ci is the tune of the Central Plains, and Yuan Qu is the tune of the people in the northern grassland, so Yuan Qu is also called Northern Qu. Yuan Qu, or Yuan Zaju, is a popular opera art in Yuan Dynasty, and it is the general name of Sanqu or Zaju. Compared with the legend of Ming Dynasty (Nanqu), later generations called Yuanqu Beiqu, which has the same literary status as Song Ci and Tang Poetry.

Ci is an art form of poetry and a style of China's ancient poetry, also known as Song Ci, Qu Zi Ci, Poetry Idle, Long and Short Sentences. Nanliang, which began in the Southern and Northern Dynasties in China, was formed in the Tang Dynasty and reached its peak in the Song Dynasty. At first, it was sung with music, so writing lyrics is also called lyrics, relying on sound. Later, it gradually became independent and became a special art of poetry.

Broadly speaking, Qu refers to all kinds of music that can be enjoyed since Qin and Han Dynasties, such as Han Daqu, Tang and Song Daqu and folk ditty. Usually, it refers to Nanqu and Beiqu since the Song Dynasty. The style of the same word is similar, but it can generally be inserted in the number of words, which is more free and more spoken. Can be divided into drama (or drama, including zaju, legend and so on. ) and Sanqu have been very popular since the Yuan and Ming Dynasties. Therefore, later generations have the name of Yuanqu.
