What is the author's style in King of the Bingo Game by Ralph Ellison?

"King of the Bingo Game" utilizes a third-person narrator who is inside the consciousness of the Bingo King. The narrator relates the Bingo King's thoughts and his memories. At first, the narration is relentlessly realistic, and almost naturalistic in its depiction of the mind of a poor, downtrodden, yet still-hopeful man. The introduction of his sick wife into the narrative gives the story a melodramatic tone.

However, as the story continues, the realism lessens and the narration approximates the consciousness of the Bingo King, becoming a mouthpiece for him as he is taken over by the power of the bingo wheel. "This is God! This is the really truly God!" the narrator tells us. "He was reborn. For as long as he pressed the button he was The-man-who-pressed-the-button-who-held-the-prize-who-was-the-King-of-Bingo." But as the story ends, the narrative voice recedes, and as the power of the wheel is separated from the Bingo King by the authorities, the realistic narration that was present in the beginning of the story returns.
