I like to go through the piece from beginning to end, under tempo, but with extremely precise rhythm and dynamics. I think it's important not to practice a difficult passage over and over again trying to get it up to tempo.... but to instead get comfortable with playing that passage slightly under tempo in its proper musical context.
It's the time frame that's giving me doubts- how do people go about preparing new repertoire to deadline?
The deadlines I have to meet are usually about 1 week or less, so you are forced to get the max out of yourself, and not put pieces on the back burner.
I wasn't sure if you are saying we should only play pieces we can sight-read fairly easily?
If so, how do we advance?
Yes, that would be ideal. Not necessarily a tempo, but most certainly with both hands without hesitation. We should at least play pieces that are not too far away from that level. Sitting months and months to learn the notes is simply abusing a work of art that was never intended to be used like that.
Thanks Dima. So essentially you're saying that in order to progress by this method I have to improve my sight-reading.
But isn't that there a risk that leads to just that - sitting on the sofa, not even attempting pieces which would be within one's grasp with a bit (I'm saying weeks not months) of practice? I'm not talking about attempting pieces which are far too difficult throughout, but pieces which one can play musically but perhaps have a few tricky patches that need work. I find that's what motivates me to improve technique.
For example, in certain Chopin etudes, it seems as if Chopin trains the "weak" fingers, while he actually requires a perfect thumb to play the work as required. If you don't realize that, it may take you 25 years of wrong training and you will still have poor results in something that seems quite playable.
Yes I could spend time improving my technique with exercises (and the kind of exercises you mention might be fun if they existed), but with a limited amount of time at my disposal, and wanting to play for pleasure, I'm not sure I could sustain motivation.
