Daoqing, also known as Daoist songs, is a kind of storytelling art used by preachers to spread their doctrines and collect donations. The "Continued Biography of Immortals" of the Tang Dynasty records: "Lan Caihe held a clapboard (a simple board) and sang and begged in the market." This may be the most specific description of early Daoqing. In the middle of the Tang Dynasty, Emperor Xuanzong of Tang, Li Longji, loved traditional Chinese Taoism very much and regarded it as the state religion. Taoism flourished for a time. Against this background, Taoism began to become popular throughout the country. Taoist missionaries traveled around the world and sang Daoqing when preaching. Daoqing was originally just a storytelling form. Before the Qing Dynasty, there was basically no professional class, and artists mostly performed during festivals to thank the gods. After the Republic of China, some places gradually developed into folk groups with professional classes and performances, and the content developed from traditional sacrifices and preaching to a variety of singing contents that the masses loved. Daoqing music is relatively rich. It is said that there are many sets of songs and tunes, but there are not many that can be sung and collected in full now. The singing style of Daoqing is a linked song, which is composed of some songs of various palace tunes connected to each other to form a large-scale singing segment with layers. Each set of songs has different songs such as positive, negative, flat, bitter, grab, and tight, and the singing style is combined and sung according to the needs of "positive and negative". "Positive" means singing in the positive tune, and the tune sung in the positive tune is generally the "Shang" tune; "Face" means singing in the reverse tune, and the tune sung in the reverse tune is generally the "Zheng" tune; "Ping" means normal emotions, and "Ku" means sad and desolate emotions, both of which are sung in the positive tune; "Tight" means the singing structure is compact, and "Qiang" means the singing structure is joyful and light. In the long history of development, Gangu Daoqing has retained its own characteristics while drawing on the singing styles of Qinqiang and local folk songs, making it a unique art with original singing style and local characteristics. Gangu Daoqing is mainly spread in Pan'an. Its lyrics include ancient traditional Daoqing, new lyrics created by the singers themselves, and lyrics composed and sung by the singers themselves. Gangu Daoqing is sung while sitting. During the performance, the rappers accompany themselves with the accompanying instruments such as bamboo boards and fish drums. The bamboo boards are two thin bamboo boards about 60 cm long and 5 cm wide, separated at the top and tied with a small bell 10 cm away from the top. The rapper holds the bamboo board from the bottom with his left hand and strikes it at an appropriate speed and beat. The two small bells collide with each other, producing a crisp and pleasant sound. The fish drum is a bamboo and wooden barrel with a diameter of 8-10 cm and a length of 90-100 cm. The upper end is covered with pig skin. When playing, the rapper holds the upper end with his left elbow and strikes the drum with his little finger, ring finger and middle finger from the lower end of the drum with his right hand. Generally, he strikes at the end of each sentence, in time with the simple board. The rappers are accompanied by the sound of the fish drum, and the strength of the strikes is consistent with the strength of the beat. When singing Daoqing, there is both speaking and singing. First, the white is recited with chanting, generally four sentences are rhymed in a group, and the last sentence is connected with a tune when it is connected with the singing, which plays a role of challenging the board. Then the simple board and the fish drum are played together to introduce the singing segment. When singing Daoqing, the dragging tune is long, melodious and graceful, and there are empty words such as Buddhist chants in the dragging tune, and sometimes others can help sing the empty words. There are many tunes in Gangu Daoqing, the most common ones are "Daoqing", "Wu Geng Pan", "Wu Geng Ge", "Chan", "Huang Gu", "Sending Books", "Eight Immortals' Poems", "Playing with Children", "Crying for Orchid Shirt", "Jiang Xiang", "Chasing Boats", "Qing Jie" and other 12 tunes.
