Zhenfeng Buyi wedding music is the music needed or used in all aspects of the traditional marriage of the Buyi people in Zhenfeng. It is widely spread in the Buyi villages in Zhenfeng County, Guizhou Province. Zhenfeng County is located in Qianxinan Buyi and Miao Autonomous Prefecture, Guizhou Province. It belonged to Yelang in the Qin Dynasty, and was divided into Zangke and Tongting counties in the Han Dynasty. It belonged to Mingzhou in the Tang Dynasty. In the early Qing Dynasty, Yongfeng Prefecture was established in Zhenfeng. During the Jiaqing period of the Qing Dynasty, a local riot occurred in Zhenfeng. Because of his meritorious service in suppressing the riot, Emperor Jiaqing bestowed the plaque "Zhongzhen Fengmao" and took the two words "Zhenfeng" in the middle to change Yongfeng Prefecture to Zhenfeng Prefecture. In the second year of the Republic of China (1913), it was renamed Zhenfeng County. The Buyi population accounts for about 41% of the total population. The Buyi people are a branch of the ancient Luoyue people. They have lived here by the mountains and rivers for a long time and are the indigenous ethnic group of Zhenfeng County. The "Guizhou Atlas" of the Hongzhi Period of the Ming Dynasty states: "When a couple gets married, men and women gather to drink and sing", "If they sing to please each other, they will discuss their looks and ask for the number of cattle and horses as betrothal gifts", etc. This shows that the marriage music of the Buyi people was popular in the marriage customs of the Buyi people 500 years ago and occupied an important position. The wedding music is wind and drum music played mainly by suona. Suona originated from Persia and Arabia and was later introduced to China. During the Jin and Yuan dynasties, the use of suona was already quite common. There were written records of suona in the Ming Dynasty. Wang Qi of the Ming Dynasty recorded: "Suona is made like a trumpet, with seven holes, the head and tail are made of copper, and the pipe is made of wood. I don't know when it started, it should be the music of the army, and now it is widely used by the people." In the Qing Dynasty, the art of suona entered a prosperous period and became a music appreciated by both the elite and the masses. In addition to being used in the court, it also showed a prosperous scene among the people. "Qing Dynasty Tongdian Music II" recorded: "During the Huamiao Festival, bronze drums and trumpets were played, and people gathered to compete with the gods. Men and women also had fun, blowing leaves and shengs, with smooth syllables, and the sound was muffled and loud, but also audible." It can be seen that suona was used in southern ethnic minority areas during the Qing Dynasty. During the Hongwu and Yongle periods of the Ming Dynasty, a large number of farmers from Jiangxi were moved to Guizhou with the army, and the military and civilian drum music of the transfer of north to south was probably introduced to the Buyi area at this time. The wedding music of the Buyi people in Zhenfeng includes mountain songs, Guwan and Leyou tunes, which are sung or played by young men and women of the Buyi people when they make friends or fall in love. The music has rich tunes and beautiful melodies. Whether it is sung or played with wooden leaves, erhu, Leyou, or moon guitar, each song has corresponding meanings. Songs are often used to represent antiphonal conversations, and the structure of the lyrics is very similar to Tang poetry. Usually, there are seven notes and four sentences in one song, which implicitly expresses the love for lovers. Among them, the "Guwan" tune sung in Buyi language is the tune of the ancient songs of the Buyi people that has gone through thousands of years. The melody is simple and elegant, euphemistic and pleasant, and it is the most ancient tune with Buyi music characteristics. Wedding music has corresponding tunes, and the layout of the repertoire corresponds to the ritual, which conveys the ritual information to the outside world. Wedding music is gentle, implicit and modest. In different eras, the content expressed by wedding music is different, and it has distinct timeliness. As an important part of Buyi culture, wedding music carries the transmission of knowledge such as agricultural science, living customs, and ethical and moral education. Its content and musical form reflect the traditional living customs, farming culture, aesthetic psychology, outlook on life and unique national character of the Buyi people. It has high academic and artistic research value for the study of ethnology, folklore, ethnomusicology, cultural anthropology and other aspects of Buyi culture. In the past 20 years, with the change of rural industrial structure and the continuous improvement of modern agricultural production level, the lifestyle of the Buyi people has undergone major changes. In addition, with the popularization of mass media and the increase in the mobility of social members, the long-standing traditional Buyi wedding customs have also changed, and from the Han customs. Buyi wedding music is now on the verge of extinction due to the loss of its own living soil.
