technical rehearsal or tech
- A rehearsal, usually held shortly before opening night,at which sound, lighting, and other technical operations are practised.The director usually runs through the show 'cue-to-cue', i.e. jumpingfrom an actor's entrance to the next sound cue, lighting change, etc.,without reading the dialogue. If actors have quick changes, however,these will be rehearsed while the text is read. A production generallyhopes to have one technical rehearsal and two dress rehearsals.
