The witches

• Instruments of darkness" (Banque Act1)
• Auditory image on "Inatrumental": 


  The auditory imagery created by the lexis "instruments" to characterise the Witches implies a malevolent musicality. This showcases how their words possess an almost hypnotic france for Macbeth.
• The choice of "instruments" suggests a deliberate orchestration of their deceit, framing their speech as a manipulative melodic composition that enchants its victims.
• Plosive on "darkness":


  The 'd' plosive sound in the word "darkness" creates a harsh sound foreshadowing the dark, ominous and grim destiny the Witches are ready to inflict upon Macbeth.
• Significantly, Banquo's discernment of this "darkness." indicates his immunity to the hypnotic and malevolent musicality that captivates Macbeth.Banquo's ability to perceive their looming malevolence distinguishes him as a character not easily swayed by the enchanting allure that Macbeth falls victim to.
• • "eye of newt", "fire bum, and cauldron bubble", and "hell-broth" (Act 4)
• Semantic field of hell: 


  The selection of words such as "fire burn," "hell-broth," and"bubble" crafts a semantic field of hell. This strengthens the idea that the Witches' supernatural abilities are intrinsically linked to malevolence and they are agents of the devil.
• • Link to context: 


  Moreover, the elements contained in their potion adhere to the archetypal portrayal of witches outlined in King James I's"Daemonologie." This conformity taps into the audience's pre-existing apprehensions and anticipations related to witchcraft prevalent during that historical era.
