What is a proscenium-arch stage? Explain what makes it unique. What are some types of machinery employed in

shifting scenery in a proscenium theatre?

What will be an ideal response?

ANSWER:Framed
by a proscenium arch, this type of theatre clearly marks the division between
stage and auditorium.
All of the seats may be on the same level or there may be one or more balconies.
The stage is designed to be seen only from the front.
This trait affects the director's grouping of actors to create stage images and the means
used to achieve emphasis and focus.
The trait also influences actors' bodily positions, movement, gestures, and use of voice and
speech.
Because the stage action is oriented in one direction, the designer frequently uses the back
and sides of the stage for the scenery, entrances, and exits.
Typically, this type of theatre features a fly system for bringing scenery in and out of the
audience's view.
The machinery for shifting scenery can also include hydraulic or pneumatic lifts,
elevators, and turntables or revolves.
