What is the author's particular stylistic??

"In Invisible Man, Ellison employs a "jazz" style in which an improvisation of rhetorical forms is played against his central theme. Letters, speeches, sermons, songs, nursery rhymes, and dreams are used throughout the novel, and the novel's style adjusts to match the changing consciousness and circumstances of the protagonist. In the early chapters Ellison employs a direct, didactic style similar to that of the social realist protest novels of the 1930's and 1940's. In the middle portions of the novel, after the narrator moves to New York City, Ellison's prose becomes more expressionistic, reflecting the narrator's introspection. In the last section of the novel, as the narrator moves toward the apocalyptic race riot in Harlem with which the novel concludes, the prose becomes surreal, emphasizing the darkly comic absurdities of American existence. In all sections the book in enriched by Ellison's versatile use of symbols that focus attention on his major themes while underscoring the ambiguous nature of experience."
