In this scenario, the key element is dramatic irony. It’s all about the two characters letting the members of the audience know how they feel about their fate without giving it away to anyone else on stage. This is effective as we can see how Macbeth and Banquo avoid showing their thoughts and emotions to the other characters. Many different techniques are used throughout this scenario which makes it easier for us to identify how Shakespeare keeps the story flowing through the use of language.

Example :  I know I am thane of Glamis;

But how of Cawdor? the thane of Cawdor lives,
A prosperous gentleman; and to be king
Stands not within the prospect of belief,
No more than to be Cawdor.

This quote tells us that Macbeth is confused as to why the witches have given him the title of ‘King’. He makes it clear that he doesn’t feel like he should be anything more than the Thane of Cawdor, therefore leading him to think that the witches are leading him onto the wrong path. At this point, the audience are left to think about whether the witches are leading him on the right or the wrong path.
