Tibetan folk songs play an important role in the Tibetan musical treasures of China. Even before the emergence of the written Tibetan language, folk songs, as a form of oral literature, had been widely circulated among the masses. Throughout the development process of Tibetan folk songs, we could observe an outline of the social history, life of various times, customs, as well as cultural and artistic evolution of the Tibetans. The main characteristics of Tibetan folk songs are liveliness, enthusiasm, simplicity, lyricism and melody.Above all, the voice is required to be natural, fluent, high-pitched and sonorous, so that it could embody the scenery of the vast blue sky on the highland with its melodious tunes. And occasionally the larynx is used to control the voice in songs with a strong style. This singing method is called “Zhengu” in folk art, a special vocal modification technique which refers to the turn of the throat. In the past, with no text transmission, the lyrics and music of Tibetan folk songs were learn by heart, spread from mouth to mouth, and passed on to the younger generation by singing by folk art performers. It is worth mentioning that the original Tibetan folk songs are not accompanied by music, but rather sung a cappella purely in Tibetan language.
