SnagWhen something gets caught on an edge or protruding screw. Can be small like a thread, or large like a set piece caught on a curtain.

Stage Manager (SM)-The person in charge of every aspect of the production. Abbreviated SM, they call cues, schedule rehearsals, and coordinate all technical elements of the show from first rehearsal through closing.
-In professional (paid) theatre, the First Assistant Stage Manager is billed as the Stage Manager. Although it’s confusing, in most non-professional (unpaid, high-school/community theatre) productions, the title of SM is used instead of PSM for the highest person on the SM team for simplicity. For more on the titles of the SM Team and the responsibilities of each member, read our article here.
Stage RightThe Right side of the stage when facing the audience (Opposite of house right)
Stage WeightA Steel plate cut to fit exactly on the arbor of a fly system. Often referred to as Bricks, there are usually two different thicknesses. The weight varies based on manufacturer, so let the Technical Director or Riggers figure exact weights based on their knowledge of the system.

StipendA set amount you are paid for the whole run of a show. Stage Managers should be EXTREMELY careful of stipends, since they are almost always taking advantage of the person who accepts the role. Calculate your pay for how much you will get paid hourly to see how bad it is. Most stipend gigs end up paying less than $3 an hour when divided out.
Strike– Removing a prop or other object from stage.
– Tearing down the set after the show closes. Usually takes a fraction of the time that building the set does.

Stumble-ThroughUsually the first run of the show, which happens when the whole show has been blocked, but not rehearsed. There are almost always a few hiccups along the way as people put the show together for the first time. Allow 20-30 minutes on top of the intended run time for the first stumble through of a full length show.

Visual CueA cue which you “Give” to a crew member to execute on their own. An example is a production with a fake light switch which the actor flips, which the SM can’t see, but the board op can. Calling “GO” for the light cue would be a guess, so instead the SM relies on the board op to take the cue as the actor flips the switch.
