‘Groove is the sense of propulsive rhythmic “feel” or sense of “swing” created by the interaction of the music played by a band’s rhythm section (drums, electric bass or double bass, guitar, and keyboards). Ubiquitous in popular music, groove is a consideration in genres such as salsa, funk, rock, fusion, and soul. The word is often used to describe the aspect of certain music that makes one want to move, dance, or “groove”.’
