Funk is an American music genre that originated in the late 1960s when African American musicians blended soul music, soul jazz and R&B into a rhythmic, danceable new form of music. Funk de-emphasizes melody and harmony and brings a strong rhythmic groove of electric bass and drums to the foreground. Funk songs are often based on an extended vamp on a single chord, distinguishing it from R&B and soul songs centered around chord progressions.
