the child doesn't mind as long as they aren't recognised, so I'll be careful what I wright, so apologies if I miss anyone's question.
Yes, it's a specialist music school, all the kids are G&T, proteges/ prodigy and mine is apparently an outlier.
Yes, it's the MDS award, all children are assessed for this and pay fees on a sliding scale, dependant on gross family income.
No, they didn't start formal lessons particularly early, there seemed little point.
I'm not sure about Nature/ nurture, we have other dc who aren't musical. Maybe they could be if they put their mind to it. I think it's probably a mix of both.
Attendance at the school was due to the child asking to go and on visiting seemed to be a perfect fit.
Ravenmum thank you 
I think they must be both at the school.
They all receive help with tuition fees (well almost)
Many are genius/ not all though.
