I was talking to a lighting designer down at Globe Theatre. I asked her if it was a possible on a stage the size of Globe's--25', close to square I think--for two spotlights to evoke two separate rooms at the same time. She said maybe, but it would be top lighting. If I wanted faces to be visible, there'd have to be lighting from the side, and one light would bleed toward the other.
To solve that problem, she said (I'm paraphrasing), what you can do is establish the cue with the top lighting, then elaborate. In other words, after you put the idea of "room" into your audience, you can play with it while maintaining the illusion.
Observations such as these help fuel what I'm up to with this musical. I do remember Sharon Pollock telling us years ago in Nelson that if you want a million birds to fly up in front of your windshield in your play, write it into the script. The director will make it happen. I know it doesn't quite work that way--Nicolas Billon told us recently that in one play he wanted a huge block of ice in which a corpse is frozen. He had to settle for a few ice cubes in an aquarium upstage center. Still, if I want two rooms, write "two rooms."
But I'm glad I asked an expert if it might work.
I was thrilled by her nod to audience. As I've tried to say before, the audience is what matters. It behooves us--it really does behoove!--not to forget it.

(And remembering now the flamenco audiences in Andalusia, which shared with performers moments of mutual need.)
