Why did the blues become a genre?

The blues emerged as a distinct musical genre in the late 19th and early 20th centuries, primarily from the African American experience in the Deep South. Rooted in African musical traditions, work songs, spirituals, and Folk Music, the blues expressed themes of hardship, longing, and resilience. Its unique structure, characterized by specific chord progressions and lyrical patterns, provided a framework for emotional expression. Over time, the blues influenced various musical styles, solidifying its place as a foundational genre in American music history.
