Swing (jazz performance style) in the context of "Kansas City jazz"

In music, groove is the sense of an effect ("feel") of changing pattern in a propulsive rhythm or sense of "swing". In jazz, it can be felt as a quality of persistently repeated rhythmic units, 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 significant feature of popular music, and can be found in many genres, including salsa, rock, soul, funk, and fusion.

From a broader ethnomusicological perspective, groove has been described as "an unspecifiable but ordered sense of something that is sustained in a distinctive, regular and attractive way, working to draw the listener in." Musicologists and other scholars have analyzed the concept of "groove" since around the 1990s. They have argued that a "groove" is an "understanding of rhythmic patterning" or "feel" and "an intuitive sense" of "a cycle in motion" that emerges from "carefully aligned concurrent rhythmic patterns" that stimulates dancing or foot-tapping on the part of listeners. The concept can be linked to the sorts of ostinatos that generally accompany fusions and dance musics of African derivation (e.g. African-American, Afro-Cuban, Afro-Brazilian, etc.).

The ska stroke up or ska upstroke, skank or bang, is a guitar strumming technique that is used mostly in the performance of ska, rocksteady, and reggae music. It is derived from a form of rhythm and blues arrangement called the shuffle, a popular style in Jamaican blues parties of the 1940s, 1950s and 1960s.
