What does the term "interval" refer to in a performance?

The term "interval" specifically refers to a scheduled break during a performance, typically lasting about 15-20 minutes. This break allows the audience to stretch, discuss the performance, or purchase refreshments. It typically occurs in the middle of longer performances, such as plays, operas, or ballets, to provide a pause before continuing with the next act or section. This is especially important in longer works, as it helps maintain audience engagement and comfort.

The other options do not accurately represent what an interval signifies in the context of a performance. For instance, a period of silence may occur at various points during a performance but does not define an interval. Similarly, while a break for actor changes can happen, it does not account for the audience's need for a break, and the ending of a performance is distinctly different from the concept of an interval. Thus, recognizing the correct definition of an interval enhances understanding of theater structure and audience experience.
