I disagree about whole class music projects, and if that is what is happening in this case, then the teacher should be writing harder parts for them.
But I think this is about general classroom music teaching in primary. I'm a music specialist, leading inset for non specialist music teachers this week funnily enough. I can tell you now, that if the teacher is not a music specialist they will be finding music very hard to teach. They certainly won't understand how they can include your kids, which they absolutely should be doing...
I absolutely believe that all primaries should have the input of a music specialist music offers so much to children....but I'd have to get on my soap box ...and that's for another thread.
Yes, I would go in. I'd be really honest and say that you know that teaching music in primary, especially at upper primary is very hard for a non specialist teacher, but your kids are losing out and they are not being stretched....and that would simply not be an issue for a specialist who would be able to differentiate the work appropriately. I'm actually at a loss how your kids are not involved in composing...their ability should be irrelevant here...children work to the level they are able to.
The other issue that will arrive on the inset this week is that teachers simply don't have time to plan and prepare for music with all the other hoops they have to jump through. Most non specialists want to open a music resource and teach from that, which will also not be challenging enough for children who have been learning instruments for several years.
I would be asking questions really, and if the school can't deliver the music teaching in an appropriate way for all pupils, they need to look for an outside provider really. But that all comes down to budget.....so. As you can see it's a very frustrating tricky situation. I have a lot of empathy for these teachers,who come into inset like rabbits in headlights.....it's gutting that more specialists aren't able to be use because of money constraints.
But yes, I would be going and having a gentle chat. I support my own child's school by regulary hooking up with their music co ordinator for chats and support. That's the other thing...who co ordinates music in the school? Dont expect them to be a music specialist, (it's often the subject everyone avoids volunteering for!)but that also might be a good starting point.
If I can help anymore, please ask x
