A new singing style in southern black communities emerged in the early 20th century, the blues. The blues brought in different musical and lyrically expressive characteristics, and was also an influence to various subsections of jazz which would come later. Due to the racial climate in the south, the institutionalization of racial segregation and forms of terrorism against African Americans is thought to have been the emergence of blues as a form of expressing their experiences in Jim Crow. Blues embodied the emotions and tones of African American life during Jim Crow from a musical and lyrical standpoint.
