Using conventional musical devices for blues compositions as a basis, Willie Dixon expanded the possibilities for blues songwriting by introducing elements from pop song forms, using a quatrain refrain text form with longer musical structures than a 12-bar form, and amalgamating the 12-bar/a-a-b form with the 16-bar/quatrain refrain form in different sections of a composition.
Dixon also helped artists such as Muddy Waters, Howlin’ Wolf, and Koko Taylor to intensify their public images; his development of their performing personae is relevant to the tradition of the blues as a secular religion, and Dixon’s casting of them originated in traditional black badman tales circulated in the postbellum South.
