What theatre term is used for the steps that actors use to move up or down on stage?

The term 'treads' is specifically used in the context of theatre to refer to the steps that actors use to move up or down on stage. Treads are typically part of a more extensive set design that facilitates smooth transitions and movements within a performance. They help create different levels in staging, which can add depth and visual interest to a production.

In contrast, 'steps' and 'stairs' are more generic terms that may not convey the specific function or design aspect of these elements in a theatrical context. 'Platforms' refer to raised areas used in staging but do not specifically denote the steps themselves. Understanding the terminology used in theatre is essential, as it allows for clearer communication among theatre practitioners and enhances the overall production.
