Funk is a style of African-American popular music originating about 1960. It resembles RHYTHM AND BLUES but is characterized by a high-volume bass, heavy syncopation with extended vamping over one funk , con or two chords, and free use of special effects from synthesizers. The lyrics are brash and often boastful. Later funk was taken over by white performers as well. Offshoots were the even more explicit Street funk of the 1970s and, in the 1980s, the revived DOOWOPis also a black slang term for the odor of sexual excitement, and by extension is sometimes used to describe any blatantly sensual song, whether rock, jazz, or disco.
