rhythm and blues

Rhythm and blues is the all-encompassing term used to describe the African-American wellspring of postwar popular music. From rhythm and blues has come rock, soul, funk, rap, and regional and stylistic offshoots. Critics consider rhythm and blues's birth to coincide with the decline of big bands and jazz's turn toward the bop emphasis on soloing. Rhythm and blues retained an emphasis on vocals while adding a more pronounced beat characteristic of the blues.
