A "Tech Rehearsal" is a practice session that focuses on the technical aspects of a performance, such as lighting, sound, and set changes. It allows the production team to test equipment and ensure everything works smoothly before the actual event. This rehearsal is crucial for identifying any potential issues that could disrupt the performance. During a tech rehearsal, all elements, including actors, stage managers, and crew members, collaborate to synchronize their efforts. This helps to create a seamless experience for the audience. The goal is to refine the technical elements so that they enhance the overall presentation without distractions.
