Funk is a music genre that originated in the mid-late 1960s when African American musicians blended soul music, 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, which are centered on chord progressions.

Like much African-inspired music, funk typically consists of a complex groove with rhythm instruments such as electric guitar, electric bass, Hammond organ, and drums playing interlocking rhythms. Funk bands sometimes have a horn section of several saxophones, trumpets, and in some cases, a trombone, which plays rhythmic "hits".

Many of the most famous bands in the genre also played disco and soul extensively. Funk samples have been used extensively in genres including hip hop, house music and drum and bass. It is also the main influence of go-go, a subgenre associated with funk.
