My DS (7) is working towards grade 2 in piano. Normally I suggest he practices specific sections again until he does it correctly but now I'm worried he doesn't have the personal drive. He is great practicing and will focus, but is nowhere near as efficient when I leave him to it. What age do you comeptely leave the practice up to them? Do you sit in the room and read a book and make small suggestions or is it 100% up to them?
