The beauty of theatre was that it was a moving, changing art form—only those who watch the same performance night in after night out see the real naturalistic drama at work—the small changes, adjustments, changes in articulation or intonation, the addition of a cough or hiccup, a longer pause rife with more (or less) meaning, the character’s movement across the stage a step slower, a step closer to the audience, the change of a word here and there, an overall change in mood and tone, the actors becoming (or not) the characters more fully, blending in with them, losing themselves in the lines, in the characterizations, in a drama that is simultaneously unfolding and becoming more and more verisimilitudinous as time marches on. This is the real narrative—while the character changes on stage in an instant, the play changes slowly, unnoticeably (unnoticeable to those closest to it perhaps), like the face of a man in his thirties, like his beliefs about life, his motives, all slowly as if duplicating itself day by day, filling itself and becoming more and more itself, the rehearsal of Self, the dress rehearsal of Self, the performance of Self, the extended performance of Self, the encore…—it appears to be the same show, played over and over again with the same details to different crowds, and yet something happens. Something changes. It is not the same show.
