What does the term chase refer to in lighting design?

In lighting design, the term "chase" refers to a sequence of lights that changes repetitively, creating a dynamic visual effect. This technique involves programming lights to turn on and off in a predetermined pattern, often to enhance the rhythm or energy of a scene. Chases can add excitement and emphasis during performances by directing the audience's attention and complementing the action on stage. This method is particularly effective in musical theatre and concerts, where synchronized lighting can significantly enhance the overall impact of the performance.

The other options do not align with the definition of a chase in lighting design. A large group of performers on stage pertains to stage dynamics rather than lighting. A style of dance performed during the show refers to choreography, which is distinct from lighting techniques. A method of stage directions involves the instructions given to performers regarding their movements and positions on stage, which is unrelated to lighting effects. Thus, the focus on the repetitive, rhythmic sequence of lights solidifies why this option is correct in the context of lighting design.
