Swing (music)

Musically, swing can be either

(written with small "s") the rhythmic feeling evoked by swinging music, esp. Jazz or
(written with capital "S") the most popular jazz style ever that prevailed during the 1930s and early 1940s. Swing evolved from jazz, but was essentially dance music and thus laid more emphasis on appealing big band arrangements than on improvisation and individual expression of the soloist. This did not prevent some of the top stars from being excellent musicians, the most notable of which is, debatably, Benny Goodman.
