Swing (jazz performance style)

In jazz and related musical styles, the term swing is used to describe the sense of propulsive rhythmic "feel" or "groove" created by the musical interaction between the performers, especially when the music creates a "visceral response" such as feet-tapping or head-nodding (see pulse). The term "swing" is also used to refer to several other related jazz concepts including the swung note (a "lilting" rhythm of unequal notes) and the genre of swing, a jazz style which originated in the 1930s.

As swing jazz was dance music and coevolved together with swing dances such as the Lindy Hop, the term swing can be understood as music that makes the listener want to dance. Even though there is overlap between these concepts, music from any era of jazz or even from non-jazz music can be said to have "swing" (in the sense of having a strong rhythmic groove or feel).

While some jazz musicians have called the concept of "swing" a subjective and elusive notion, they acknowledge that the concept is well-understood by experienced jazz musicians at a practical, intuitive level. Jazz players refer to "swing" as the sense that a jam session or live performance is really "cooking" or "in the pocket."
