The witches’ use of incomplete trochaic tetrameter in Macbeth creates an unnatural, unsettling rhythm that reflects their supernatural nature. The irregular meter contrasts with the more orderly speech of other characters, emphasizing the witches’ ability to disrupt natural laws and control fate. This jarring rhythm adds to the foreboding atmosphere, making their speech sound ritualistic and otherworldly, and foreshadows the chaos they will bring to Macbeth’s world. Their language underscores their power over the natural order and enhances the mystical, eerie tone of the play.
