Poetry has never been divorced from music. The earliest poems were all used for singing. After the establishment of the Western Han Dynasty, culture began to spread, and scholars created a large number of poems. However, the development of music failed to keep up, and the form of poetry gradually separated from music and began to recite independently.
Although the flat and flat meter was put forward in the Tang Dynasty when the modern poetry was formed, the ancient poetry was not without rules, and the Yongming style before the meter poem had begun to abide by the four-tone meter. Moreover, after the elimination of the Millennium, with the Sanqu attached to those ancient poems before the Han Dynasty, those poems that are not easy to read, have no aesthetic feeling of language, are not easy to recite and are not easy to circulate are gradually eliminated and forgotten. However, some written records still exist. When we read it today, we will find that the level and level are not smooth, because when singing, the words will change tone, and we don't have to follow the tone of Chinese characters. Of course, the tones of Chinese characters may have changed greatly for thousands of years.
This is very similar to the current lyrics. Popular songs, besides the final rhyme, pay more attention to the tone of music, without considering the influence of the pronunciation of Chinese characters themselves.
During the Wei and Jin Dynasties, Cao Zhi developed Bai Fan, and Shen Yue's four-tone verse initiated the application of "top-down" in poetry creation. On this basis, the court poets in the early Tang Dynasty combined the requirements of rhyme, antithesis and number of words to create several metrical forms such as quatrains, metrical poems and arrangements. Xu, the prime minister at that time, found that these four kinds of rhymes were more complicated than metrical poems, so he presided over the compilation of a verse at the behest of Wu Zetian. This book directly simplifies the four-tone rhyme against metrical poetry into flat tones, and divides the "flat" and "rising tone into tone" in the four tones into flat tones. This is the origin of today's Ping, and it is also the basis of Liu Yuan's Ping Yun Shui in the late Southern Song Dynasty.
Relatively speaking, although modern poetry later became the main means of the imperial examination, which forcibly promoted the development of flat and even metrical patterns, and metrical patterns were indeed a good tool suitable for poetry creation and fluent sentence-making, in personal creation, poets like Li Bai did not care about flat and even metrical patterns when their poetic hearts broke out. Poetry expresses ambition. Although the standard is good, it is naturally unnecessary to limit all forms of expression to four or eight sentences. Therefore, free-form classical poetry and elaborate modern poetry have always gone hand in hand and developed together.
But it can't be said that it has no effect at all. After the mature metrical style, the ancient style will more or less follow the rules of flat and flat, because these rules are summarized and refined from ancient poems. Classical poetry can't achieve word equivalence and rhyme in the end, but it still has to change its tone with people's back. On the other hand, your classical poetry is anti-human and will be spurned and eliminated.
Strictly speaking, that kind of free classical poetry is still declining. Its decline lies in the fact that its own artistic conception of Gu Zhuo cannot return with the refinement and refinement of human society. In fact, there are two trends in ancient customs after the Tang Dynasty. One is ancient style. Even if it doesn't keep a flat and even format, it won't rhyme to the end. However, the written sentence pattern of "Neatly Placed" has no miscellaneous words and long and short sentences.
The other evolved into "Yu Shi", which directly gave birth to another brilliant metrical style "Song Ci". In addition to the looser rhyme than modern poetry, the number of words in Song Ci is also limited to music. After the great integration of Sui and Tang Dynasties, Hu Yue constantly invaded China culture, and the modern and global music cultures were greatly integrated. The emergence of new styles such as Song Ci, Yuan Qu and modern poetry was only a historical necessity.
As for the so-called "ancient style poems" written by modern people, most of them want to write ancient style poems, but they are unwilling to delve into the meter, write something that looks ancient and non-ancient, and pile up some words to entertain themselves.
There's nothing wrong with it.
