Sitting song hall is the essence of the ancient culture of the Yao nationality and one of the forms of Yao nationality singing. The Yao nationality villages in Xintian County are located at the junction of Xintian, Changning, Guiyang, Qiyang and Ningyuan counties, forming a cultural circle with about 40,000 people speaking "Mianyu" (Guoshan Yao language). Therefore, the Yao family sitting song hall here has become an indispensable cultural entertainment form for the Yao nationality to "accompany guests". The Yao family sitting song hall consists of eight parts, such as "entering the village, offering cigarettes, tea, persuading wine, fate, thanking the master, and parting and seeing off". The songbook is passed down orally and in handwritten copies, and the tune is passed down orally and memorized. The inheritance pedigree is relatively complex, generally family inheritance. There are also Yao song lovers who ask for advice when visiting relatives and friends, and most of them are amateurs who learn in production and life and collective activities. The basic characteristics of sitting song hall are "ancient, numerous, wide and beautiful". First, the tune is ancient. As a part of the regional culture, Yao songs have been passed down for thousands of years and have lasted for a long time, and their inheritance has not changed to future generations. Therefore, it can be said that it is a "living fossil" of the tunes left by the ancestors of the Guoshan Yao to their descendants. Second, the lyrics are rich in content. Astronomy and geography, calendar, animals and plants, riddles, the birth of Pan Wang, etc., can all be answered in Zuogetang. It can be said that Zuogetang is a place to impart various knowledge. Third, it has a wide coverage. National culture has its regionality, and is often confined to a certain place and ends. And Zuogetang is spread with the flow of people. Fourth, the melody is beautiful. The music score is ancient and elegant, gentle and beautiful. The singers strictly follow the Yao language "according to the ancient pronunciation" to pronounce words and rhyme. They choose lyrics according to their moods, and their emotions come from their hearts, infecting all listeners, making them unforgettable. Zuogetang, with a large number of lyrics and self-contained tunes, is the remnant of the "Yao songs" and ancient music of the Guoshan Yao culture. It is worthy of being a treasure of Yao culture, with high research value and aesthetic value in music, anthropology, linguistics, and folklore.
