Comping. Comping is a term used in jazz music to describe the chords, rhythms, and countermelodies that keyboard players or guitar players use to support a jazz musician's improvised solo or melody lines. The term is also used for the action of accompanying, and for left hand part of a solo pianist.
The pianist's primary job is to play chords (the music that accompanies the melodies) in a lively, rhythmic fashion. This is called comping. Notice how it comes from the word accompany.
