In the play Macbeth, William Shakespeare establishes an eerie atmosphere using characters and setting. Shakespeare begins by setting the play in a location with heavy weather. The play commences with “Thunder and lighting”(1.1.0). This sets the mood for the act, providing an unusual setting to accompany the mysterious witches, which the act immediately follows up on. As Shakespeare brings the three witches into the scene, he provides little knowledge about the witches. This gives the witches a peculiar presence that definitely adds to the act’s atmosphere. The dialogue the three witches use also adds to their presence because of their strange vocabulary. Their strange vocabulary begins when the first witch speaks and states “I come, Graymalkin”(1.1.9).
