The Mask Technique is an actor training discipline that has its origins in the work carried out by Jacques Copeau in France at the beginning of the 20th century, later continued by his disciples, such as Jacques Lecoq, Ariane Mnouchkine and Mario Gonzalez, among others. This work resulted in modern schools of learning the art of theatrical representation, where the mask and the body are the main references of a system that is inspired by Ancient Greek Theater and Commedia dell'Arte, but also by the forms of Popular Traditional Theater present a little throughout the world, and in particular in Eastern countries, such as Topeng in Bali or the Japanese Noh Theater. The use of the mask and the traditional representation of these theatrical forms requires the actor to know and master a set of rules and learn a body and mental discipline that will be useful for the exercise of his profession both in theater and cinema or On TV..
