Thanks again Salzberg for the good information. It seems to me that if it's just a matter of setting the sound/lights (after having pre-planned them) we should have enough time with a 6 hours' tech, as long as I get to do a spacing rehearsal with the dancers the previous day. I am just not used to predicting how long it takes to switch gels & all the technical stuff, which (in my somewhat limited experience) seems to vary greatly from theater to theater -- & I suppose depends on how quickly the crew can do it.
The theater director was concerned 6 hours wouldn't be enough (they usually do 10) so I hope to talk with her again this week; there could be factors I'm not aware of. I don't know if we could walk in with a disk but hopefully we could. We really don't have sets or props so far. So far I have been relying on costumes & lighting (&, hopefully, dancing!) in creating the atmosphere & I kind of like the simplicity of that. I love costumes!
You ask really good questions, by the way.[/QB]
I tend to be kind of obsessive about these things but it often seems to help the result...
