The idea of a neutral mask for actor training was originated by Jacques Copeau and effectively disseminated throughout the world by Jacques Lecoq.
The neutral mask is intended to provide for an actor the basic principles of playing action necessary to play any style of theatre. These masks are based on the masks used at the Lecoq School in Paris.
Sears Eldredge say this of neutral mask: “It attempts to erase the individuality; to get at the essence;to get at man rather than this man.”
The neutral mask is not a mask worn on the surface it is one that come from deep within and so an great tool for training actors.
