Ask my brother and sister to help translate it into Chinese.

Use mine. I tried to explain its historical background, hoping to help you.

Music appears in many forms, and most countries (in this case, countries should be countries) have their own styles. At the turn of the century when jazz was born, America didn't have its own excellent music. No one knows exactly when jazz was created and by whom. However, it attracted attention in the19th century. Jazz is America's contribution to pop music. Unlike classical music with formal European traditions, jazz is spontaneous and free. It is full of energy, expressing people's emotions, interests, emotions and so on. 191920s, just like representing America. It still is.

The origin of music is as interesting as it is. Today, black Americans, or blacks, are pioneers of jazz. They were sold as slaves to the southern States (the United States was divided into north and south). Before the North-South Railway Station, the southern part of the United States was mainly slave owners, mainly plantations, and the main labor force was bought African slaves. Landlords advocated feudal slavery in America, which greatly hindered the development of free trade in America. On the contrary, the North advocated free trade and opposed slavery, and the contradiction between the two sides intensified, which led to the American Civil War. They were sold to plantation owners and forced to work long hours. Whenever a black man dies, his friends and relatives will line up and carry his body to the cemetery. In New Orleans, a band often follows these parades. On the way to the cemetery, the band played slow and solemn music suitable for this occasion. But on the way home, my mood changed. Cheer up. Being busy with death took away one of their companions, but the living are happy to be alive. The band played pleasant music, improvised harmonious melody and the mood of attending the funeral. This music makes everyone want to dance. This is the embryonic form of jazz.
