It was a high ranking form of theater, which contradicts it’s slapstick, exaggerated comedy. The actors often changed characters throughout performances by putting on a new mask, which were distinctly recognizable not only from exaggerated features (i.e nose, ears etc.) but from character's stance as well. For the most part the “script” was only a guide, a bare story. The actors largely improvised their lines.
Commedia dell'Arte was performed by elitist groups of actors in the mid 16th century. They moved around from town to town, setting up temporary stages and platforms. The use of costumes and masks were crucial to conveying characters and meaning. Audience members would laugh at the mere appearance of performers.
Actors
Acting troupes performed in environments such as marketplaces with loud and distinct voices, as to match the bustling nature of the town. Slapstick and physical comedy were highly prevalent during performances. Often story lines were about the demise of an individual, but in a funny manner.
The Masks
The “Masks” used in performances did not change between different plays and venues. Consequently, there is next to no character development throughout performances as this would be altering the nature of the mask. Hence, there is an absence of cathartic processes, and psychological progression is not possible.The actors must totally immerse themselves in the mask, and must not alter the thought process or actions representative of their character.
