A technique, used by jazz pianists, of playing syncopated chords at irregular time intervals is known as: comping
What is Comping?
Comping in jazz refers to the chords, rhythms, and countermelodies that keyboard players (piano or organ), guitarists, or drummers utilize to enhance a musician's improvisational solo or melody lines. Comping can also be derived from the verb to "supplement."
Additionally, it refers to the left hand of a solo pianist as well as the accompanying motion.
During the horn and double bass solos in a conventional jazz combo, the pianist or guitarist usually provides accompaniment by improvising chords and countermelodies.
Several popular music genres, including rock and folk, utilize a chordal accompaniment style that is different from the chordal accompaniment used in jazz.
