A pupil of mine was playing this to me this afternoon, and automatically took the demisemiquaver B flat in bar 9 with her left hand. This worked well and, to be honest, I didn't even notice until she told me what she had done. My question is - would she be penalised for this in the exam. Also, should she be consistant and take the other notes of similar rhythm with the left hand, although she feels this is awkward. Or should she train herself to take the original B flat with the correct (right) hand?
