According to the census data of 2009, the Nùng ethnic minority had a population of 968, 800 people and was the seventh most populous group in Vietnam, who mostly live in the provinces of Lạng Sơn and Cao Bằng. The Nùng people have a rich treasure of folk culture and folk songs imbue with their group. Bụt (the Goddess of Mercy) is one kind of religious rituals of the Nùng people. In everyday life, the Nùng people believe that men have thirty hồn (souls) and women have forty vía (vital spirits). Hồn vía are associated with body. When the Nùng deal with difficulties, the soul and vital spirits escape from the body, making the body ill. If the soul and vital spirits leave the body for a long time, the person will be severely ill or die. At the beginning of spring, the Nùng people often worship for vital spirits at home. This worship includes twelve phases with singing meaningful lyrics. The singing melodies have many pitches—low, high, deliberate, strong, enthusiastic, passionate tunes, etc.—bringing deep emotions to people’s hearts. The song “Bụt lằn” (Expressing spring scenes) with lyrics on plants, flowers, and animals, paints a natural scene that is fervid and harmonious with the thoughts and feelings of the people, evoking a sense of honesty, talent, and intelligence.
