Theatre is art.
It reflects life, selecting and focusing on part of the total picture, and this selectivity is a key principle in theatre. The impulse toward theatre is universal and has appeared wherever human society has developed. Rituals, religious ceremonies, and celebrations have certain elements of theatre, including a performance in front of an audience, costumes, scenery and storytelling. Theatre is a transitory art that occurs through time. A theatre performance changes from moment to moment, and a theatre event is created by cumulative sights, sounds and impressions.
