Supernatural Connection and Manipulation Tactics
The witches don't just work alone - they share an unnatural mental connection that's genuinely unsettling. When they chant "Fair is foul, and foul is fair" in perfect unison, Shakespeare is showing us something impossible for normal humans.
Speaking the exact same words simultaneously isn't just coincidence - it's supernatural. This synchronisation hints at their otherworldly powers and immediately makes them untrustworthy characters. A Jacobean audience would have linked this to devil worship, making anyone connected to them (like Macbeth) seem cursed.
The witches also use rhyming patterns that connect across speakers - Witch Two says "When the battle's lost and won," and Witch Three continues with "That will be ere the set of sun." This isn't normal speech; it suggests their words are rehearsed and planned.
This rehearsed quality is crucial because it shows the witches have been preparing for Macbeth's arrival. They're not reacting to events - they're orchestrating them through equivocation (deliberately ambiguous language designed to mislead).
Remember: The witches' unnatural speech patterns and shared consciousness make them seem like one entity with three voices - much more threatening than three separate individuals.
