the cast , orchestra , set decorators , costume designers and stage crew were all expected to move from city-to-city , performing three times daily the same actions : the orchestra producing the same notes with the same timbres , volumes , and intensities ; the stage hands repeating the same motions with the same sets and props , over and over , following the same mindless routines ; the actors and singers voicing the same lines again and again and again and again , in the same way and from the same positions on stage : but all of this for different faces each evening , for different people who would receive these actions and gestures and moments and musings as though they were new and coming into existence for the very first timeof course , the audiences would be cognizant enough of the devices of theater to know otherwise , but these fantasy-seeking spectators also enjoyed giving in to that suspension of disbelief which allowed them to entertain temporarily the possibility that these moments they were witnessing were unique and nearly impossible to replicate .
