The difference between regular verses and quatrains is: regular verses are metrical poems with eight lines each, while quatrains are metrical poems with four lines each.
1. Rhymed poetry is a genre of traditional Chinese poetry, which belongs to the category of modern poetry and is named after its very strict metrical requirements. Rhymed poetry has strict regulations in terms of words, rhyme, level, and antitheses. Its common types include five-character poems and seven-character poems.
Example: Li Bai's "Send Off a Friend"
Green mountains stretch across Beiguo, and white water surrounds the isolated city.
This place is different, and I have to conquer thousands of miles.
The thoughts of wandering in the floating clouds, the love of old friends in the setting sun.
I waved my hand and went away, the horse roared.
2. Quatrains, also known as truncated sentences, broken sentences, short sentences, and quatrains, are a form of modern poetry. Various schools have different interpretations of it. Some people think that "half of the rhythm is cut off" so that it can be sung in music. Quatrains are composed of four sentences, divided into Lvjue and Gujue, among which Lvjue has strict metrical requirements. Common quatrains include five-character quatrains and seven-character quatrains, while six-character quatrains are relatively rare.
Example: "Listening to the Zheng" by Li Duan
The zither is played with golden millet pillars, in front of the jade house with plain hands.
If you want to get Zhou Lang's attention, you always mistakenly play the string.
Rhymed poetry originated from the new style poems of Shen Yue and others in the Qi Yongming Dynasty of the Southern Dynasty that emphasized rhythm and antithesis. It was further developed and finalized in the Shen Quan period and Song Zhiwen period of the early Tang Dynasty, and became popular in the Tang and Song dynasties.
