Until the 195s, Tibetan society had been in a closed state, and its music remained in an inherent traditional form for a long time. From the classification point of view, the traditional music in Tibet is generally divided into four types: court music, folk music, religious music and drama music. In addition, there is a dichotomy, which classifies drama music as folk music. Palace Music The palace music in Tibet generally refers to the music for cloud music and dance in Potala Palace in Tibet in the middle of last century, and also includes the music for cloud music and dance in the palaces of the living buddhas in various temples. Although "Zan Bougourd Lu" appeared in the Tubo Dynasty, its music (score) has not been seen because it is limited to the lyrics, so it remains to be verified. Music for Yunle Dance can be divided into three types: Gaer (dance) music, which is a kind of free, broad and long song and dance music, and is often played by instruments such as Suna (wind music), Dammam drum and clarinet. -"Gaerlu" (song) music, which is a beautiful and elegant "Gaerlu" song, is often accompanied by instruments such as Zan Nianqin, dulcimer, Biwang (string), flute and Genka (string). —— Welcome drum music and light playing music belong to pure instrumental music. Among them, welcome drum music is often played by instruments such as "Su Na", Damma drum and clarinet, while light playing music is often played by two instruments such as clarinet and Damma drum. Palace music is a kind of high-style traditional music in Tibet, and its content is often religious or eulogizing. In the past, the performers who performed music and dance for the clouds were all men to show the holiness and sacredness of religion. Folk Music Folk music occupies a large proportion in Tibetan traditional music, ranking first among the four categories of Tibetan music in terms of variety, quantity, content richness, coverage and performance frequency. In terms of genre, folk music can be divided into five categories: song and dance, folk songs, labor songs, rap and instrumental music. -Song and dance music. Tibet enjoys the reputation of "the ocean of singing and dancing", where there is a song and there is a dance, there is a song, and singing and dancing has become one of the greatest characteristics of Tibetan music. This feature is caused by the special geographical environment and lifestyle. As we all know, the Qinghai-Tibet Plateau has a high altitude and a cold climate. It has become a routine for people living in this land to dance involuntarily every time they sing songs, day after day and year after year. On the one hand, the content of the song is vividly expressed by "dancing", and on the other hand, it will achieve the effect of heating, which is also one of the special functions of Tibetan song and dance art.
