The Buyi Eight-tone Sitting Singing is also called "Buyi Eight-tone", which is a form of folk art and rap passed down from generation to generation by the Buyi people. For thousands of years, it has been passed down in every village and hamlet in the Nanpanjiang River Basin. It is said that the prototype of Buyi Eight-tone belongs to the court music, which is mainly played by wind and percussion. After the Yuan and Ming Dynasties, due to the role of the Buyi national aesthetic consciousness, it gradually developed into a form of music performed with string and bamboo instruments as the main accompaniment. According to relevant records, Buyi Eight-tone was once popular in the Ming and Qing Dynasties. In the Buyi villages in the Panjiang River Basin, there are generally music teaching workshops "Bayin Halls" to teach Buyi Eight-tone skills. There are more than 300 Eight-tone teams performing Eight-tone Sitting Singing. After the founding of New China, the Buyi Eight-tone Team in Xingyi City was invited to participate in performances at home and abroad many times, and was praised as "Panjiang Wonder", "the last sound in the world, the sound of nature", "the living fossil of sound", and "the artistic pearl on the Nanpanjiang River". The performance form of Eight-tone Sitting Singing is that eight people hold eight kinds of musical instruments, such as Niuguhu (ox-horn hu), Huluqin (gourd hu), Yueqin, Cigu (bamboo drum), Xiaotong, Chai, Baobaoluo, Xiaomaluo, etc., and sing in a circle. The performance starts with the first person "jumping in" to sing and narrate the story, and the third person "jumping out" to explain the story. There are also cases where Buyi instruments such as Lelang, Leyou, and Muye are added for accompaniment. When singing, male artists mostly use high octaves, while women sing in the original tune, which can not only produce a strong contrast in pitch and timbre, but also increase the interest of singing. The singing tunes of Eight-tone Sitting Singing are mainly [main tunes], and other tunes are collectively called "idle tunes". The most representative traditional programs include "Buyi Wedding Customs", "Hexitang", "Hu Xi and Nanxiang", "Welcome Tune", "Singing the Story of Wang Yulian", "Toasting Song", "Liang Shanbo and Zhu Yingtai" and more than 40 other programs.
