The history of jazz in the 1920s always ran on two separate tracks: black jazz on the one hand, white jazz on the other, and really very seldom they crossed paths.
These were almost two separate forms of art, happening in very different environments and following very different performing practices.
Black jazz was much more intuitive, was often more lively and relied on call-and-response both among musicians and between performers and audience.
White jazz sought more symphonic orchestrations, tended to be more mellow and less syncopated, and the call-and-response especially between performers and audience was less prominent.
In many respects, it could be argued that white jazz in the 1920s was less revolutionary than black jazz, and still it was far more popular and received a lot more recognition.
One of the reasons is that the first instrumental recordings specifically labelled ‘jazz’ featured the Original Dixieland Jass Band, a white band from New Orleans lead by Nick LaRocca. This record was a huge success, it sold over one million copies and made jazz known to a wide public, even the one who didn’t frequented nightclubs and speakeasies.
Although subsequently many black jazzmen recorded their music, white musicians had always an easier access to recording.
One of these musicians, Paul Whiteman, is probably the most popular of his time. In the 1920s, he was the King of Jazz in most people’s mind. Besides, a large part of the public didn’t’ even have access to black-and-tan and black clubs, where most black musicians were more popular. Slumming was in vogue, but only a small amount of the public actually did it. So, between the limited access to authentic black jazz and the actual attempt at appropriation that white musicians and especially white critics were pursuing, a large part of the 1920s public were never aware that jazz had originated in the black community and was still prominently an African American form of art.
Some white performers perfected what became known as ‘nut jazz’. They consciously distorted blue notes and turned them into grossly exaggerated groans, growls, moans and laugh.
On the other side of the spectrum, other performers adopted the opposite strategy and ‘diluted’ or ‘refined’ blue notes by de-emphasising them. Because this kind of jazz was what was more often recorded (because it was played prominently by whites), it was also what became more popular, which marginalised most black and some white musicians who remained wedded to participatory and improvisational jazz performance.
