Bach is a German composer and is known as one of the greatest composers in the history of Western music. The number of his works is extremely large, and more than a thousand of his works have survived and been cataloged by later generations. Bach's music creation process is more like that of a meticulous craftsman than an artist. His music combines the musical styles of different ethnic groups in Western Europe and combines the essence of traditional Italian, French and German music.

Bach did not enjoy great fame during his lifetime. But in the past century and a half, his fame has continued to grow, and he has even been evaluated as the greatest composer in the history of Western music.
