CallQ – Stage Management Training Software

Calling a busy show can be difficult. Learning to call can be even tougher.
Your brain needs to be doing a number of things simultaneously; listening to what’s happening on stage, watching the stage or monitor, listening to your operators and reading the prompt book. This doesn’t even include being interrupted side-stage by an actor who has lost their handkerchief.

Recently, I took over 1984 mid-tour, a technically tough show. I spent weeks at home practicing the call and cue lights. I made myself a paper cue light panel and sat with the archival and prompt book calling the cues. Sure, it worked, but what if you could learn the show, or learn how to call, using software that is a calling simulator? Thanks to CallQ, you now can.

Gail Pallin,  stage management teacher and author of Stage Management: The Essential Handbook, together with partner and software developer Iain, have created CallQ – simulation software that teaches the user how to call a show. Prompt-side recently got in contact with Gail to find out more about CallQ and what it can do for Stage Managers.

Calling a show for the first time can be scary. ‘I can still feel the fear and anxiety of hoping I would get it right,’ Gail recalled of her first call in college. ‘Not disadvantaging the performers and maintaining the integrity of the piece was incredibly stressful.’

Also, training institutions are limited in the number of productions they can produce in a year, meaning that only a few students get the opportunity to learn to call. Gail says CallQ can provide ‘an opportunity that offers every student one equal cueing experience, which can be assessed and ensures parity across the year group.’

CallQ has two versions – CallQ Trainer allows the learner to learn calling on a pre-recorded show, while CallQ Studio allows you to record your own show then run it through the software, meaning you can train someone new to call the show, or for use in remounts.

Gail explains that the software is more beneficial than traditional calling practice (such as me using the archival at home), because you can ‘practice cueing without expensive show conditions. Students can cue over and over in their own time until they feel confident with their technique.’

So, how does CallQ work?

Using a PC or Mac, the program gives instructions on what to do, then gives the caller FOH clearance. ‘Once they have accepted clearance its up to them to start the show by standing by the operators,’ She says. ‘The software plays a film of the show (as a backstage monitor) and reacts to the cue light instructions. The operators acknowledge the standbys via the cue lights and verbally. The play begins and you cue the show according to the prompt copy.

‘If you cue incorrectly (miss a cue, too early, too late) the program will stop, explain your mistake, set you back to the previous stand-by and you can try that sequence again. Once you reach the end of the show successfully, it prints out a show report which details miscues etc.’

‘Over 50 professionals and 30 students have trialled this and they all felt nervous when the film begins and plays the audience murmur and shows the tabs and tab warmers (which proves how realistic an experience it is)!’ says Gail.

And where does she see CallQ going in the future? ‘I would love to see every drama school and college using [CallQ] in addition to the standard cueing exercises and production opportunities already offered. It would also be useful for interviewing show callers and would hope that producing companies would give to young graduates joining that company one of their own shows to cue to help build confidence before their first professional show.’

CallQ is now available here.

After training many Stage Managers over the years, I also asked Gail a few questions about learning Stage Management in general, you can find a profile of Gail here.

Gail and Iain are looking for a few more shows to film to add to the software, if you know of any professional production that would be happy to be involved, please contact

A Beginner’s Guide to Cans Etiquette

On a big show, there’s nothing worse for operators and Stage Managers when someone on cans isn’t adhering to standard etiquette. Not only does it hamper everyone’s ability to do their job properly, but it makes for a cranky Stage Manager (SM). And a cranky SM is akin to the Fun Police. At a basic level, most people in theatre are here because it’s fun. But if the Fun Police are out in force, it becomes just another job. And it should (always) be more than that.

For the uninitiated amongst you, ‘cans’ is a common name for communication devices used backstage in theatre, which consist of a pack (sometimes radio and sometimes wired) and a headset. If you are calling, it may consist of a headset and a panel in your SMD. The term ‘cans’ comes from the old system of two cans on a piece of string.


Cans are also sometimes referred to as ‘comms’ or ‘headsets’.

In Australia, it’s usually the sound department’s responsibility to maintain the cans system, and they should be your first port of call if your cans are not working properly.

So, how to use your cans without bringing the cranky fun police knocking on your door?

What you need to say

When putting your headset on: (your name) on cans. 
It’s important to know at all times who is on cans with you.

When taking your headset off: (your name) off cans
Again something I insist on, as the SM needs to know if one of their operators or crew isn’t contactable for a time.

When an SM says “Standing by LXQ8”: Standing by or LX
For all cues, this should be your response. The general rule of thumb is that if the SM is only standing one operator by, you can say ‘Standing By’. If the SM is calling multiple operators, you should respond with what you are operating. For example, the dialogue should run like this:
SM: Standby LXQ21, SDQ35, Door to open and FLY Q3.
LX operator: LX
Sound operator: Sound
Mechanist: Door
Flys: Flys
This enables the SM to know exactly who is standing by. It’s tricky for an SM to know who is standing by if a couple of people say ‘standing by’. I always smile when people respond in the same order as the call (because it satisfies my obsessive compulsive personality), but it’s probably too much to expect that it should always happen.

Can I Talk?
This is a great question. If you need to say anything that isn’t urgent (even if it’s show related), it’s great to check with the SM if it is a good time to talk. You will notice that this is a question used a lot by people who are used to working on big shows, or have been around a while. Take note, they have learnt over the years the value of this question. Learn from their wisdom.

What you shouldn’t say


No-one should say GO except the Stage Manager. Try to avoid saying it in conversation, or when describing something that happened. Good operators have excellent reflexes when they hear the word Go and it can end in a mis-timed cue. Yes, it happens.

Anything other than your response between the ‘standby’ and the ‘go’.
I have seen this cause so many problems on shows where someone has tried to crack a joke between the standby and the go, and one of the operators has pressed ‘go’ in response to something in the joke. Just don’t talk while everyone is on standby. It’s a simple rule that gets broken all the time. It’s not okay (unless in an emergency).

Any type of gossip.
You never know in a venue where people can hear you. In a lot of the major theatre centres, you can turn on the cans feed from various theatres in the management offices. Other offices have _squawk boxes_ that play the cans feed through a speaker so anyone popping into the office can hear it, or sometimes even walking by. It’s equally important not to talk about actors or performers on stage. On more than one occasion I’ve witnessed the crew talking about how awful an actor is while the actor was sitting in the lighting office and they heard everything.

Anything when the SM says ‘Quiet Please’
Calling is hard sometimes. It involves a lot of listening. If the SM needs some quiet to hear the dialogue, or just to concentrate for a moment, they will say ‘Quiet Please’ and this is everyone’s cue to shut up immediately. If you need to say something, go back to the ‘Can I talk?’ question.

When to be on cans:

The SM will often do a cans check before the show to make sure everyone is at their post. If you are an operator, you should be on cans from the five minute call for each act. If you are an ASM, you should be on cans before the house is open.

Other things to know:

  • When talking to someone who isn’t on cans, don’t take your headset off. I’ve been known to say someone’s name repeatedly to get their attention, to find out that they are chatting to someone else and have taken their cans off to hear better. This is also not okay. If you’re on a quiet show, ask the sound department for single ear headsets. This way you can turn your free ear to the person talking and you don’t have to take off your headset ever.
  • Technical rehearsals are very busy for everyone involved, best to not chat at all during these times.
  • SMs have different preferences. I quite like a bit of cans chat when the time is appropriate. It can keep a tired crew engaged when they are starting to flag. Other SMs prefer silence. Respect the wishes of the SM. They are responsible for keeping the whole show together, so if they ask for silence, give them silence.
  • Warn people before unplugging your cans. It can make a deafening pop.
  • Some venues run a few loops. On big shows, the SM will not listen to some loops. Be aware of who you are trying to talk to and which loop they are listening to.
  • Turn off your mic if you need to cough or yell. It is also deafening.
  • Don’t leave your mic open if you are not saying anything. People don’t like to hear you heavy breathing or rustling around backstage. I’ve also experienced the full soundscape of someone using the toilet. It isn’t nice.
