Sound and Lights
While the dancers are training, musicians practicing their timing, set designers are coordinating the backdrops and set pieces, and the principals are memorizing their lines, the sound and light crew are busy ensuring microphones work, sound equipment like microphones and sound boards are working properly, lighting cues are perfectly timed, and the light colors reflect the mood of the show. An ill-timed light could leave a principal in the dark during a key scene.
A missed light or sound cue could change the entire tone of a pivotal moment. Sound and lights are one of the most crucial elements to creating the tone and setting of the scene and require a highly technical mind to work equipment like that in the photo. If they’ve done their jobs right, the audience will be able to read the main character’s emotions not just by the actor’s work, but through sound and visual cues.
