I have a problem with how to eliminate errors – wrong notes, rhythm not smooth, inappropriately accented notes etc.
I have been trying to eliminate the last few errors from a piece I learnt recently. The first half of it is fine. The second half is in three sections all of which are quite fast but not technically difficult. (I always find fast pieces difficult, but I usually get there in the end with a lot of practice.) When playing the piece at the speed I want it to go I found that usually two of the three sections in the second half would go well, without any mistakes but that I would make two or three mistakes in the other section. But it would be a different section that would go wrong each day, or each practice session.
Because there were relatively few errors and they changed all the time, it was hard to pin down where the problems were. So I decided to ‘stress test’ all three sections by playing them about 2 metronome notches faster than the speed I wanted and making a note of all the mistakes. There were quite a lot so I spent a long time working on each one – taking a few bars around the mistake, playing it slowly and in some cases hands separately, making sure it was accurate and then gradually ramping up the speed to the stress test speed. When I had finished one section I put it all together and played it successfully at my normal speed before going on to the next section. I worked through all three sections like this over several days. Then the next day I tried playing the whole piece through. The first half was fine as usual but, to my surprise and dismay, all three sections in the second half suffered catastrophic failure. I suppose I must have “tested it to destructionâ€! There was every imaginable error in almost every bar.
It didn’t get any better when I tried it on subsequent days, so I decided to give it a complete rest for 10 days and instead focussed on my new pieces. Then when I tried it again it had miraculously mended itself – well almost. I am now back exactly where I started, with a small number of errors in one of the three sections each time, with the other two sections going well and very smoothly. But as before, the bad section is different each time. Maybe the good sections sound a bit better than before (when they are good), but maybe that’s my wishful thinking. I’m wondering what to do now.
Any ideas would be greatly appreciated. Thanks.
