What is the primary purpose of stage directions in a script?

The primary purpose of stage directions in a script is to provide performance instructions. These directions are crucial for actors, directors, and stage crew, as they offer guidance on how to physically portray the actions of the characters, where they should move, and how they should interact with their environment and fellow actors. This can include notes on body language, emotional tone, and even specific movements or gestures that are important for conveying the story effectively.

Stage directions are not primarily about developing the plot, which is typically conveyed through dialogue and character actions rather than instructions from the playwright. While they can help to set the scene and create mood, their main function is to guide the performers in their execution of the script. Additionally, while stage directions may sometimes include character introductions, this is usually not their primary role. Instead, the dialogue is often used for character development, while stage directions serve to enhance the overall production by facilitating a coherent and dynamic performance.
