* Rhythm: The story is written in a deliberate, measured rhythm that mimics the beating of a heart. This rhythm creates a sense of foreboding and builds suspense as the story unfolds.
* Repetition: Poe uses repetition throughout the story to emphasize important ideas and create a sense of circularity. For example, the word "house" is repeated over and over again, reflecting the central role that the Usher mansion plays in the story. The phrase "the fall of the house of Usher" is also repeated several times, foreshadowing the inevitable destruction of the house and its inhabitants.
The use of rhythm and repetition in "The Fall of the House of Usher" creates a powerful and unforgettable atmosphere that stays with the reader long after they finish the story.
