I do lots and lots of accompaniment for my pupils but find it really hard to listen to them as much as I need to and play the piano at the same time.
It often goes like this - we set off together, pupil makes a couple of mistakes, I start listening hard to what they are doing and lose concentration on the piano!
My accompaniment is absolutely fine in the exam and the 2 or 3 "dress rehearsals" we do in the lead up to the exam as there aren't so many mistakes being made and I know the pupil knows the piece well, so I concentrate on playing.
Any tips? Am I perhaps introducing the accompaniment too early? Though my teacher used to accompany me from the first day a piece was introduced and never really pointed out mistakes. I don't want to be accused of spoon feeding but I feel it is my duty as a teacher to point out mistakes being made and help to correct them.
