Dongjing music, a folk music popular among the Han, Bai and Naxi nationalities in Yunnan Province, China, was originally a Taoist ritual music, and it was named after its content of singing the scriptures of Wenchang Dadong Fairy Classic. The production of this music is not recorded in historical records, but it should be closely related to the production, spread and evolution of the immortal sutra of Wenchang Cave, which was preached and sung, and the "Huang Jing". "Jing Jing" is a general term for the whole religious etiquette activities, also known as "doing things". "Jing Jing" activities are usually held in temples or temples dedicated to gods, and the duration is usually three or five days. The content varies according to the different scriptures sung. Dongjing music includes a variety of musical expressions such as blowing, pulling, playing, playing and singing, which is mainly divided into vocal music and instrumental music. The vocal part is called "jingqiang", also known as "jingqu". Its lyrics are similar to poems in verse, and there are several structural forms such as four-character sentences, five-character sentences and seven-character sentences. The first part of the scripture is in the form of prose, which is the part of preaching and reading. From the structural form and performance form of scripture, it is similar to the "Bianwen" in the Tang Dynasty and the "Baojuan" (a folk singing form developed from the "vulgar talk" in the temples in the Tang Dynasty). There are two forms of band accompaniment when singing "Jing Qiang": one is accompanied by a silk and bamboo band, the other is accompanied by a percussion band, and the latter is mostly used when opening or closing the classics. The instrumental part of Dongjing music is called Qupai. Qupai is mainly used for the music of various ceremonial activities, such as opening the altar, collecting scriptures, offering sacrifices to gods, offering offerings, reciting profound and magnificent tables, etc., and also for the interlude of classics.
