I've had children in various performing arts.
In a lot of way the teachers can be caught between a rock and a hard place.
They pick the same kids, then everyone says it's favourites and unfair.
They give everyone the chance and they may end up with a poor production and then parents pull their children out because the show was "rubbish". Yes, that does happen, seen it several times.
The extra singing = parts can be one of several reasons:
- Those who are good tend to have extra lessons
- Those who have singing lessons are better because... they have singing lessons, and possibly teach them for the audition
- The children who have singing lessons have pushy parents who will make a fuss if they don't get the main part
- They give main parts to the children who have extra lessons because they want them to keep paying.
I've seen all of those happening at various places.
It isn't just talent going into the auditions. It's also how well a child listens to instructions, are they likely to panic on the day, are they unreliable (I've been at a dress rehearsal where the main part didn't turn up with no warning), how well do they work with their opposite number etc.
There can with a known group also be a bit of history-she did particularly well with her small part last year, let's give her a big part this time; he refused to wear the costume last year because he didn't like the hat, let's avoid the part with a major costume.
You can also have the situation that they're very keen to give new people the chance to see what they can do (and keep them coming back :D) so the regulars get bumped down each year.
With one of mine I was fairly sure she was given some of the parts because she was very good at herding/encouraging the younger ones and they wanted her off stage to do that at certain points.
Yes, I would pull her out and look for another if she's asking. But don't get your hopes up it necessarily will change.
What I would look for is:
Camaraderie: When they're encouraging each other and cheering for each other. Fingers crossed all watching in the wings because their friend finds this bit difficult is lovely. Yes there might be a bit of rivalry too, you'll never eliminate that, but when they work together and want to see each other that's good. Ds came out from his first session back saying "it was brilliant except X wasn't there." Not that X is his best friend, but he missed them because they are part of the group/
Fun: A great show is one thing, but how did they get there? You want to see the children going in running and calling to friends, and coming out laughing and full of adrenalin.
Control: A theatre can be dangerous. You want the leaders to be in control. I've chaperoned when the leaders are not in control and it's not fun for the children or anyone else. You want so that if they say "lights down, stand still" that one doesn't decide to see what happens if they jump off the stage, knocking the others in the way."
Performances: Some places go for lots of performances, drama festivals etc. Some don't. I don't think it really matters, but your child may love or hate them.
So look at a few and decide what you want from it. Give her the chance of picking from some, but sometimes the little independent ones can be better than big franchise-and sometimes the franchise ones are great! Give them both a chance.
