Passing a solo back and forth in four-bar turns. One musician improvises four bars, another answers with the next four, and they alternate through the chorus while the form of the tune keeps running underneath. Most often it pairs a horn player with the drummer, but any two or more players can do it, and the count can be changed — trading eights, trading twos, trading whole choruses. The point is conversation: each four bars is heard as a reply to the four before it, so the players are quoting, answering and needling each other in real time.
“After the second chorus they started trading fours with the drummer, and he answered every phrase the horn played.”
Origin & Attribution
The practice grew out of the call-and-response habits Black musicians carried into jazz from the church and the blues, and it hardened into a named routine among Black bandleaders and soloists in the swing and bebop years. Swing-era bands were already building exchanges into arrangements — Count Basie's Lester Leaps In in 1939 and Duke Ellington's Cotton Tail in 1940 both turn on players answering one another in short spans — and the four-bar exchange became a standard, expected part of the arrangement in the bebop scene of 1940s New York, on 52nd Street and in the Harlem after-hours rooms. It did two things at once: it gave the drummer a solo voice inside the form instead of a break outside it, and it let players contest one another openly, which is why the head-to-head version between two horns is called a chase. The most-cited recorded instance is The Eternal Triangle, cut for Verve in New York on 19 December 1957, where Sonny Stitt and Sonny Rollins trade fours at a punishing tempo before Dizzy Gillespie enters. One correction: trading fours is often taught as a bebop invention, but the exchange habit predates bop by at least a decade in Black big-band practice. What bop supplied was the name, the speed, and the expectation that it would happen every night.
