The music of the Sui Dynasty was influenced by the folk music of the north and the old music of the Song and Qi Dynasties of the Southern Dynasties. The court music and songs were mixed with "Hu sounds". After the Sui Dynasty destroyed the Southern Dynasty, the Qing Commercial Office was set up to manage it. During the reign of Emperor Yang of the Sui Dynasty, nine music groups were established: Qingyue, Xiliang, Qiuci, Tianzhu, Kangguo, Shule, Anguo, Gaoli, and Libi. At that time, the musical instruments included the pipa, the vertical-headed harp, the Tara drum and the Jie drum, all of which were passed down from the northern peoples and the Western Regions. At that time, it was already known that the musical scale had seven tones instead of five.

Wanbaochang and He Tuo were famous musicians in the Sui Dynasty. He Tuo was from He country (located in today's Uzbekistan), and he was also good at philosophy. In 592, Dr. Yi Guozi was ordered to formulate Zhengle. At that time, all the important ministers discussed it a lot, and Wan Baochang also participated in the discussion, but there was no result for the time being. In the end, He Tuo used a trick to get Emperor Wen of the Sui Dynasty to use Huangzhong Palace to resolve the dispute. He Tuo also made the royal chariot "He Tuo Cha" for Emperor Yang of Sui Dynasty. He is the author of books such as "Le Yao" and "Book of Changes".

Wan Baochang is the author of "Music Score". At that time, Emperor Wen of the Sui Dynasty was troubled by Hu music and the "sound of national subjugation" in the Southern Dynasty. In order to formulate the official music, he summoned Niu Hong, Xin Yanzhi, He Tuo and others to rectify the music and produce national music that was suitable for the Sui Dynasty to unify the world. At that time, the important ministers Zheng Yi, Su Wei, He Tuo and others discussed for a long time without reaching a conclusion. Although Wanbaochang expressed his opinions, his status was low and his suggestions were not adopted. However, he obtained the consent of Emperor Wen of the Sui Dynasty and used the "water ruler law" he proposed to modulate the instrument. Although Wan Baochang was ambitious, he died of frustration due to the jealousy of some powerful people. His music was said at the time to be "the music of the Western Regions, the music of the barbarians, and not suitable for sergeants." "Sui Shu Music Records" also mistook the eighty-four tunes as Zheng's theory. In fact, this is the research result of Wanbaochang.
