Before a play is performed, it is rehearsed.
Rehearsals are the process of practicing and refining the various aspects of a play such as dialogue, blocking, lighting, sound effects, and stage design. During rehearsals, the actors work on their performances and interactions with each other, the director makes adjustments to the script and the production team work on perfecting technical elements.
Rehearsals are crucial to ensure that the play is as polished and professional as possible before it is presented to the audience. Without rehearsals, the performance would be much more likely to have mistakes, and the overall quality of the play would suffer.
