As Melvin Gibbs shows in How Black Music Took Over the World, it is the musical inheritance of Africa. Beginning with two rhythmic building blocks he calls the cell and the frame, Gibbs shows how those tools can transport listeners to “a realm where sounds become vehicles for human movement.” Reforged in the African diaspora in the Americas, they are played today on church organs, electric guitars, computers, telephones, or a simple gourd. Kool & the Gang called Black musicians the “scientists of sound”—and Gibbs shows how they discovered the world’s music.
