set, props, actors) come together to run through the play from start to finish, not only to get issues such as set and costume changes finalized and timed correctly, but to smooth out any minor issues with lighting, sound, tempo, etc. Tech rehearsals – rehearsals where the actors are not involved. They give the sound, lighting, and running crew a chance to rehearse and create a rhythm that is proficient and smooth prior to dress rehearsals. Run-throughs – The meaning of this term depends on the director. Generally, it can mean just running through an act with the actors (no technical aspects involved). Sometimes it can involve costume changes, as those can become complicated if wig changes are also required. Costume changes can be rehearsed and done in as little as 30 seconds to 2 minutes (if a wig is involved).
