As the musicians became more skilful they quite naturally wanted to show off their new powers and extend their gift still further, and they couldn’t very well do this in the tight, intricate New Orleans ensemble. This trend away from the old style really got under way soon after the main group of musicians spread northwards from New Orleans. What has been called ‘Chicago style’, for instance; played by both white and colourect musicians, often amounted to a string of solos by trumpet, trombone, clarinet, saxophone (usually the tenor) and piano, with an ensemble chorus (chorus means, in jazz terminology, one complete section of twelve or thirty-two bars) to start and finish the whole thing, like the bread round an outsize sandwich.
