The sound of the quotation from Edgar Allan Poe's "The Fall of the House of Usher" is best described as "discovery." At the same time as explaining the vision, the narrator expresses his thoughts about seeing it. He has no idea what these emotions are or what "sinking, sickening of the heart" means to him. "What was it (...) what was it that so unnerved me in reflection of the House of Usher?" he wonders. He concludes that it is a mystery, and that a different arrangement of the items in the scene and the specifics in the painting may change the picture's somber tone.
If the narrator of a fictional piece is not a character in the story, the statement about the narrator that is true is that the narrator speaks using an authorial voice.
