The origin of the Blues can be traced back to the post - Civil War era. African - Americans, who were formerly slaves, had to deal with poverty, discrimination, and difficult living conditions. The Blues was their form of musical catharsis. It often had simple chord progressions like the 12 - bar blues pattern. Musicians used their voices, guitars, and sometimes harmonicas to create this soul - stirring music that was passed down through generations.
Definitely not. Biloxi Blues is purely fictional. It's a creation that might draw inspiration from various elements but doesn't represent actual happenings in reality.
