2. Words are a kind of 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 Sui Dynasty, took shape in the middle and late Tang Dynasty, and flourished in the Song Dynasty. During the Sui and Tang Dynasties, the national music imported from the western regions gradually merged with the old music of the Central Plains, and Hu music was the main music that produced Yan music. The original neat five-character seven-character poem is no longer suitable, so there are words with different words and more lively forms. Ci originated from the folk, and later literati wrote new words according to the rhythm of music score, called "Ci" or "Qu". Since then, words have been separated from music, forming a kind of metrical poem with irregular sentences. Fifth, the seven-character poem is symmetrical and dual, presenting the beauty of neatness; The characters are mainly long and short sentences, showing uneven aesthetic feeling.
3. Words have epigrams, that is, tunes. Some intonations have different "styles" because of different words or sentence patterns, and there are about 100 commonly used aphorisms. "Qinyuanchun" is a epigraph. There are also "Xiao Ling", "alto" and "long tune". According to Mao's Ci Xie in Qing Dynasty, words below 58 are small notes, words between 59 and 90 are medium notes, and words below 90 are long notes. The longest inscription, Preface to Bird Singing, has 240 words.
4. A epigraph reflects a certain sound and emotion, and the origin of the epigraph name is mostly unknown. Only a few talented words such as "Bodhisattva Man" and "Qin Yi E" have rhyme, which is where the music stops. Generally don't change the rhyme. Some words are promises, some words are promises, and some words are promises. Like five-character poems and seven-character poems, the words are even and even, and the pronunciation should be divided into three parts: upper, lower and middle, and the words can overlap.
Because most of the ci poems in the late Tang Dynasty, the Five Dynasties and the early Song Dynasty were written for entertaining guests before the banquet, there is a saying that "ci is a path, colorful" and "poetry is charming". With the development of Ci, Liu Yong and Su Shi gradually expanded the theme of Ci until Xin Qiji reached the peak and became a literary genre with the same status as poetry.
