Why rap music is a black patent?

There are several reasons for this. First, from a social point of view, Rap rap music originated in poor black neighborhoods in the United States. Many black people can't afford to go to school, have no jobs, and suffer from racial discrimination. In addition, there are many gangs, which mix many types of music with black roots and produce hip-hop music (blues and soul music in the history of western pop music are all blended from African black folk music). They express their sadness, sadness and cynicism in this way. Secondly, according to the characteristics of race, the sense of rhythm and the grasp of language rhythm of most blacks in the United States are innate. These black tongues are softer and more flexible than those of other races, and they can pronounce a series of dense words faster. In addition, because rap originated from black Americans, there are many black rappers.
