Final answer:
The blues genre developed from the experiences of African-Americans, drawing from their history of enslavement, oppression, and the search for civil rights.
Step-by-step explanation:
The blues developed out of the experiences of African-Americans. The genre has its roots in the African American history of enslavement and oppression, as well as the struggle for civil rights and equality. This shared racial experience, despite manifesting in various forms across different times and locations, centers around racial oppression and has influenced the thematic and emotional depth of blues music. The blues, as a music genre, grew from African spirituals, work songs, shouts, chants, and narrative ballads, embodying elements of both African musical traditions and the hardships endured under American slavery and subsequent societal challenges.
