What metaphors are used in Jazz by Toni Morrison?

Over the course of the novel, each new chapter is introduced by a somewhat more subdued tone. We see the narrator losing much of her cockiness and sense of superiority. As the narrator ponders the complexity of Joe's motives, she introduces a new tone of authorial uncertainty: "I've wondered about it." Despite her claims that she knows Joe well, she understands him as a stereotype, a "black there fore blues man" and can only offer the notion that the "City spins you" once one gets on the City's metaphorical track, as the explanation of the inevitability of Joe's killing Dorcas.
