Ballet, also known as dance drama, is a synthesis of dance, drama and music. It is a stage art that uses dance and mime to express artistic images with the cooperation of music. Pantomime uses movements and expressions to express the plot without using lines. The original ballet began to develop based on folk dance in the Italian and French courts in the 16th and 17th centuries. Later, he entered the theater, often interspersed in operas and various plays. It was not until the beginning of the 19th century that it developed into an independent art; however, operas after the 19th century still often included ballet. Originally, ballet music was a stylized thing written according to choreography. There is no close connection with each other. Later, composers made various reforms to ballet music, making the music subordinate to the expression of dramatic content.
