The Bulang people mainly live in Menghaihong County of Xishuangbanna Dai Autonomous Prefecture in western Yunnan, Shuangjiang, Yongde, Yunxian, Gengma in Lincang, Lancang, Mojiang and other counties in Simao. The Bulang people have their own language but no written language. Some people are fluent in Chinese, Dai and Wa. The Bulang people's singing and dancing art is rich and colorful, and is greatly influenced by Dai songs and dances. Among them, Bulang folk songs are called "Bulang tunes", which are rich in content and have many tunes. Whenever they get married, move to a new house, celebrate the New Year or work, Bulang young people love to sing. In 2008, Bulang folk songs were selected into the second batch of national intangible cultural heritage protection list in my country. There are four categories: "Shuo", "Zai", "Suo" and "Zui". When singing, the tunes of each type are almost unchanged, and the content is improvised according to different occasions. The "Shuo" tune is accompanied by a small three-stringed instrument, mainly singing the love content of young men and women, and it is full of passion and youthful vitality. The "Zai" tune is also accompanied by the Xiaosanxian, and is mostly sung in duet by young men and women. The "Suo" tune is also accompanied by the Xiaosanxian, and is mainly about folk customs. The "Zui" tune is sung in duet during festivals or celebrations, and mostly praises the deeds of historical heroes and historical figures. These tunes also have their own characteristics due to regional differences. The Bulang tunes in other regions include folk songs, mountain songs, fighting songs, lanterns and suonas. Folk songs are short and powerful, lively and brisk, and are accompanied by gourd shengs. There are many mountain songs, which are mainly sung in duet by young men and women when working in the mountains. Fighting songs are short and brisk. The lantern tune is light and cheerful, with a strong sense of rhythm, and is mostly accompanied by erhu and Xiaosanxian. Suona tunes are usually played with both hands, and the local Bulang people call it "blow and beat", which is mainly used for weddings and funerals. The Bulang folk songs originated early and spread widely. They have unique classification habits. Although they are influenced by many cultural factors of the Dai people, they still maintain their unique and distinctive national personality. Most of the Bulang folk songs are in the Yu mode and Gong mode. The melody often uses "56 by Jie 236" as the backbone pattern, and is mainly based on the pentatonic progressive mode. The melodic interval is more common with minor third and fourth leaps, and only in children's songs occasionally there are sixth leaps. The melody is flexible and changeable, the phrases are long, and they are mostly connected within the octave, and a small number of them reach the eleventh range. The commonly used beats are 2/4, 4/4, free scatter, and constant variable beats with initial beats. The folk songs of free scatter do not have a rhythm of repeated strong and weak beat cycles in units of bars, and the contrast between light and heavy beats is not large. Its dynamic factors depend on the physiological limitations of the singer's breathing; the constant variable beat can be divided into bars, but because the stress appears in the uneven rhythm, the length of the song bars is uneven, and the time signature changes frequently. The musical form structure is mostly a structure that changes and repeats itself constantly, with the upper and lower sentences corresponding to each other as the basic unit. There are many supporting words and tunes at the beginning and end of the song, which makes the Bulang folk songs particularly interesting and lively, and has become its distinctive feature. The singing methods of Bulang folk songs include solo, duet, one leading and many singing, and singing while dancing. Among them, the leading singing part is an impromptu singing with a relatively free rhythm, while the singing part is relatively fixed. The lyrics are mostly three, five, or seven words per sentence, and metaphors are often used. Bulang folk songs sung during festivals and entertainment are often accompanied by percussion accompaniment and simple dance movements, with singing and dancing, and a strong festive atmosphere.
