How is laughter typically used in theatrical performances?

Laughter is often employed in theatrical performances primarily as a method to engage the audience. It serves to create a connection between the performers and the viewers, fostering an interactive atmosphere where the audience feels involved in the storytelling. When laughter occurs, it signals that the audience is enjoying the content, thus reinforcing their attention and emotional investment in the performance. Humor can break the tension in a narrative, allow for moments of relief, and provide a counterbalance to more serious themes, ultimately enriching the overall experience of the performance.

In contrast, while other options might touch on aspects of theatre, they don't encapsulate laughter's primary role as effectively. For instance, obscuring the plot wouldn't align with the intention of most theatre, nor would laughter typically enhance dramatic tension, as it often serves to relieve it. Similarly, while laughter can contribute to character development, it is not its principal function in most theatrical contexts.
