I am the parent of an 8 year old (September born) who passed grade 1 in the summer. Her teacher has given her a new piece (A Sad Tale, Kabalevsky) which she's just learning. She's doing very well with it but it seems a massive step up from G1 and having a look on Youtube it seems it was a G4 Trinity piece in 2012/14.
This jump seems excessive and I can see that it's going to take her a while to get to grips with it. She's also going through Czerny and some much easier pieces but I wondered if it was, if not normal, not unusual for to be given a much harder piece along with easier music.
Just for non-drip feeding, her teacher praises her musicality and this is a very expressive piece and technically she's good on sight-reading etc... but she's hardly ever played a piece perfectly all the way through (hesitation and a funny panic when she thinks too hard - like her perfectionism is actually hindering her ability to play fluidly). I wonder if this is too much, too soon.
