The first scene is full of influence even if it is short. Only thunder and lightning can make it a dramatic beginning. And because it represents evil, it attracts the attention of the audience. These dramatic sound effects help Shakespeare create a strange and supernatural atmosphere that they want to create with witches. The Shakespeare audience is facing three seemingly strange women, not Macbeth. The witch introduced us a dark, dangerous drama centered on the theme of evil.
The audience measures the content of the drama using the first scene of the drama like the first scene of Macbeth. Among them are talks about magic, evil, violence and things, but they do not look like 'foul is fair, fair is foul'. This scene is short enough to give you a glimpse of the witches and the fact that they participate in the performance, but their purpose and what they can not think of. They are enigmatic and will let you think about what they are telling them.
In the first scene of the first act, three witches plan to meet next time, they will meet Macbeth. It is this scene that jewels are presented, as the witches in the tree sing "Fair is foul, foul is hovering in fair, fog and dirty air". The witch met again in the third game of the first act. She refused to share her food, so one of the witches discussed her curse on her female husband. This evil power and malicious behavior suggest that witches have some influence on the development of this theme. In this scene, Macbeth entered Banquo and arrived from the battle of victory. Using this theme he explained that day "It is a very bad and fair day, I have never seen it" (1.3.38). When Macbeth encountered a witch, they made two predictions to him. One is that he will be Cawdor, then King of Scotland
