The palace music system of the Sui and Tang Dynasties was the "bureau music system".

Not long after the establishment of the Sui Dynasty, the Yanle system of "Buyue" was promulgated in the form of decree. This is the Sui Dynasty court Yan music with the name of the country and place as the music section, including Qing music (traditional music), Xiliang (now Gansu) music, Qiuci (now Kuqa, Xinjiang) music, Tianzhu (India) music, Kang Guo (i.e. Kangju, today's northern Xinjiang and Central Asia) music, Shule music, Anguo (Central Asia) music, Gaoli music, and Libi (the last one played is called Wen Kang music). In the early Tang Dynasty, it was changed to "Ten Music", including Yanle (mixed Chinese and foreign music), Qing Shangji (traditional old music), Xiliang Ji, Tianzhu Ji, Gaoli Ji, Qiuci Ji, Anguo Ji, and Shule Ji, Kangguo Ji, Gaochang (in today's Xinjiang) Ji. Qingyue or Qingshangjie has preserved the traditional old music since the Han and Wei dynasties. The music they play is re-created based on foreign music, and retains many aspects of foreign music, and still bears the name of a foreign country or a foreign nation. Since the Han and Wei dynasties, a large amount of foreign music has been absorbed and digested, which is one of the conditions for the high development of musical art during this period.

In the eleventh year of Zhenguan (637), Emperor Taizong of the Tang Dynasty abolished "Libi". In the fourteenth year, "Yan Yue" was listed as the first part, forming the "Nine Parts of Music" in the Tang Dynasty. The "Yan Yue" in the nine-part music is different from the broad meaning of palace Yan Yue, but is a specific name of the music part. During the Zhenguan period, "the scenery and clouds appeared and the river water was clear", Xielu Lang Zhang Wenshou produced "Jingyun River Qingge", named "Yan Yue". This is a music and dance that promotes the achievements of emperors and praises the peaceful and prosperous times. It is generally performed on solemn occasions.

In the 14th year of Zhenguan, Emperor Taizong of the Tang Dynasty unified Gaochang. In January of the 16th year, "Gaochang Music" was established as an independent music club, forming "Ten Music Clubs". The ancient Gaochang State was located in Turpan, present-day Xinjiang, and was one of the transportation hubs between China and the West in ancient times. Its music style is close to that of Qiuci music, which to a certain extent reflects the characteristics of the fusion of Chinese and Western music cultures.

At the time of Emperor Gaozong, it was divided into two major departments: "Zuo Bu Ji" and "Li Bu Ji" based on the characteristics and performance forms of music, singing and dancing. There are fourteen pieces of music and dance based on the sitting and standing movements. There are eight pieces of Libu Ji and six pieces of Sibu Ji. Most of these music and dances were produced during the four dynasties of Taizong, Gaozong, Empress Wu, and Xuanzong, which was the period when the Tang Dynasty's national power was at its strongest. Their content mainly focused on praising the merits and prosperity of the ruling class. The music style is as mentioned in the "Old Tang Book·Music Chronicles": They all beat big drums, mixed with the music of Qiuci, the sound shook hundreds of miles, and the valley was shaken; Dading music was added with golden horns; only Xiliang music was used to celebrate the good music. , the most elegant. "From Changshou Yue onwards, Qiuci music is used in all performances. All dancers wear boots. However, in "Longchi Yue", the Yale Sheng and Chimes are used, and the dancers tiptoe."
