I want to know what dances and music were popular in the Tang Dynasty! Please give us your advice!

During the Sui and Tang Dynasties, the political power was unified, especially in the Tang Dynasty, with political stability and economic prosperity. The ruler pursues an open policy and constantly absorbs other cultures. In addition, the fusion of various ethnic music cultures since the Wei and Jin Dynasties laid the foundation, and finally sprouted the peak of all-round development of music art with song and dance music as the main symbol. The music enjoyed by the court in the Tang Dynasty is called "Yan Yue". Seven-step and Nine-step in Sui and Tang Dynasties belong to Yan Music. They are folk music of various nationalities and some foreign countries, mainly including Shang Qing music (Han nationality), Xiliang music (now Gansu), Gaochang music (now Turpan), Qiuci music, Guo Kang music (now Samarkand, Uzbekistan), Anguo music (now Bukhara, Uzbekistan), Tianzhu music (now India) and Koryo music (now North Korea). Among them, the more important ones are Qiuci Music and Xiliang Music. Yanle can also be divided into Zuobi and Bailey. According to Bai Juyi's poem Bailey, the performance level of his left arm is higher than Bailey's. The popular song and dance Daqu in Tang Dynasty is a wonderful flower in Yan music. It inherits the tradition of Xianghe Daqu, and integrates the essence of national music in nine pieces, forming a structural form of scattered sequence-middle sequence or beat sequence-breaking or dancing all over. There are 46 Tang Daqu's in Jiao Fanglu, among which "Dancing in Dress and Feather" is praised by the world because of its elegant style, which was written by the famous imperial musician Tang Xuanzong. Bai Juyi, a famous poet, wrote a vivid poem "Yi Yu Dance Song" to describe the performance process of this Daqu. Pipa is one of the main musical instruments of the band in Tang Dynasty. Its shape is almost the same as today's pipa. Nowadays, Fujian Nanqu and Japanese Pipa still retain some characteristics of Tang Pipa in shape and playing method. Influenced by Qiuci's music theory, the 84-tone and 28-tone music theory of Yan music appeared in the Tang Dynasty. In the Tang Dynasty, Cao Rou also founded the Guqin notation of subtraction notation, which has been used until modern times. At the end of the Tang Dynasty, there was also a popular musical, which had a story, roles and makeup performances, singing and dancing, and both accompaniment and orchestral accompaniment. This is a small-scale embryonic drama, such as bedding face, stepping on mother, dialing head, joining the army and so on. Tang poetry, a must in the history of literature, was able to sing and laugh at that time. At that time, geisha often sang famous poems quickly; After entering the profession, poets also measure their writing level by the popularity of poems. The prosperity of music culture in the Tang Dynasty is also manifested in a series of music education institutions, such as teaching workshops, pear gardens, big music departments, preaching departments and pear gardens dedicated to teaching young children. These institutions have trained a batch of talented musicians through strict performance assessment.
