Yes, we've agreed that she is going to discontinue lessons in June. This is a natural stopping point that makes sense to all three of us. She is still hunting for a guitar teacher.
I'm just looking for some of the little miniatures that she seems to actually LIKE working on so that she doesn't feel as though this last few months is either useless or torturous. Those Bartok pieces (Op 56) are the bomb for her, but she plays the entire set well enough that she could (IMO) probably play them at competition level NOW if that were her thing.
