參考翻譯
Quyi refers to folk vocal art forms such as ballad singing, story-telling and crosstalk. As an ancient performing art in China, quyi is a general term that covers several different types of performances in which speech, singing or both are used. As an independent art, it was formed in the middle Tang Dynasty and flourished in the Song Dynasty. Deeply taking root in China, the art is divided into three styles and subdivided into 400 parts. The three major styles are story-telling, story-singing, and joke-telling. Story-telling can be either words only, or words with music. One of the most representative non-music styles in the North is called Pingshu. The most important form of joke-telling is crosstalk. Story-singing seems to have the largest audience. Each style has a strong local flavor in either its accent or music.
