how insightful!
I am not going to tell you out of what material an artist of the theatre of the future will create his masterpieces. Out of ACTION, SCENE, and VOICE.
When I say action, I mean both gesture and dancing, the prose and poetry of action.
When I say scene, I mean all which comes before the eye, such as the lighting, costume, as well as the scenery.
When I say voice, I mean the spoken word or the word which is sung, in contradiction to the word which is read, for the word written to be spoken and the word written to be read are two entirely different things.
