I'm teaching some new students who are very young but very advanced and have some problems that cannot be fixed in a short time. They have been pushed through exams every year, and this year is no exception. I'm finding out they have poor practise habits (practising to them means playing the entire piece a few times at top speed regardless of mistakes), and technique (some very poor hand positions and fingering). They do have their strengths of course or they wouldn't have come so far. I'm not used to this -I'm used to teaching the correct hand positions and hand movements in order to get the proper sound. But I can't correct these things since it would take a lot of time, hand exercises and devotion on their part, and right now there's only time to get them to learn their pieces as well as possible in time for the exam. So I have to just focus on surface things and a few of the really obvious technical problems. I am teaching them proper practise techniques. Has anyone else been in this position and how did you handle it? How do you correct a bad hand position that a student has been used to using for years? Also I don’t want to weigh them down with too much technical correction. I think I’m sometimes overly focussed on that anyway. Any tips would be much appreciated!
