Groove (music) In music, groove is the sense of propulsive rhythmic "feel" or sense of "swing". In jazz, it can be felt as a persistently repeated pattern. It can be created by the interaction of the music played by a band's rhythm section (e.g. drums, electric bass or double bass, guitar, and keyboards). Groove is a key of much popular music, and can be found in many genres, including salsa, funk, rock, fusion, and soul.
