In musicals, what does the term "segue" refer to?

The term "segue" in musicals refers to an act or scene that immediately follows another, creating a smooth transition between the two. This can involve a seamless flow in dialogue, music, or choreography that maintains the audience's engagement and ensures the performance moves forward without interruption. In musical theater, effective segues are essential for keeping the pacing of the production tight and enhancing the storytelling experience, as they help to connect different elements of the narrative or musical numbers fluidly.

The other options pertain to different aspects of theater production; for instance, a set that is used for the entire performance does not relate to the concept of transition between scenes or acts. A break for set changes indicates a pause rather than the continuity that a segue represents, and specific types of lighting address technical elements that enhance the visual aspect of the performance rather than the narrative flow.
