What does "fast fade to" refer to in lighting/sound terms?

"Fast fade to" refers to a quick transition in either lighting or sound, where the existing light or sound level reduces rapidly rather than slowly. This technique is often used to create a dramatic effect or to signify a change in scene or mood within a performance. When transitioning swiftly, it can give the audience a sudden shift in atmosphere, which can be very impactful in theatrical storytelling.

The concept of a “fast fade” specifically indicates that the transition is not drawn out, but rather achieved in a concise manner to maintain the pace and energy of the performance. This is very different from options that describe a slow fade or an instant act, which do not capture the nature of a quick transition. Such distinctions in timing and approach to fades are crucial in the context of stage design and production, affecting how an audience perceives changes in the narrative.
