Scenography is called both the art and technique of design and decoration of scenic spaces, as well as the resulting set of visual elements that allow in a realistic, ideal or symbolic way the place in which an action takes place and that constitute a scenic production. These elements can be corporeal, as is the case of the set and props; lighting, characterization of the characters including costumes, makeup, and hairdressing are also included. It can also be defined as the staging of various live shows, including theatre, dance, opera, zarzuela, circus, etc.

The scenery is made up of those visual elements that are part of the staging, such as the set, accessories and lighting. It is important to point out that scenery does not only exist in theater, cinema and television since, in addition to the cases mentioned, there are also scenery, TV programs that are not fiction, such as newscasts or a journalistic program.

The first signs of stage design date back to the theater of Ancient Greece. However, it should be noted that the Greeks, whose civilization has undoubtedly had a considerable influence on very diverse fields such as language, politics, education and the arts, went a little further: creating an artifact called periact, which has the ability to alternate the decorations depending on the need of each scene.

For a long time, the most common method of changing or hiding scenery was by deploying a curtain in the background. Nowadays, however, the use of panels and walls is quite common, to change it much faster.

Within a theatrical work, the scenery plays a very important role, even for those who claim to place their attention exclusively on the actors and musicians, according to the type of presentation that corresponds. The secret is not found in the abundance, nor in the attention paid to each detail or in the quality of the materials, the secret is in the validity that each element seems to have within the context of the work itself.
