What is the court music and dance in the Tang Dynasty?

In terms of music and dance, the Tang Dynasty inherited and carried forward the traditional culture, with a broad mind and a combination of Tibetan and mining, forming the third peak after the Western Zhou Dynasty and the Western Han Dynasty. The court music and dance in the Tang Dynasty can be divided into five categories, one is to enjoy the banquet music and dance, the other is to enjoy the commercial music and dance, the third is to enjoy the music and dance of the surrounding ethnic minorities, the fourth is to play all kinds of music, and the fifth is the elegant music for sacrifice. Some feasts and dances were left over from the previous generation, while others were made in the Tang Dynasty. Music and dance in the Qing Dynasty was an ancient music in the Southern Dynasties. It leveled the world in the Sui Dynasty and collected its achievements, which remained in the Tang Dynasty. The music and dance of the surrounding ethnic minorities were very complete in the Sui Dynasty, and it was not until the Tang Dynasty that a tune was added. Three kinds of music and hundreds of plays are the collection of three kinds of music in past dynasties. Sacrificial music and dance, also known as elegant music, is only used for sacrifice, with fixed lyrics and high and low music. This paper briefly introduces three types of music and dance: banquet music and dance, commercial music and dance and the surrounding ethnic minorities' music and dance.
