well, he said it is good for my weak fingers to be stronger.
but I am sure this is an old idea
Does "my weak fingers" mean, the fingers on the weak side of the hand (4 and 5) or, all fingers are weaker than optimum?
dear rocket 88
my resource is a book by georgy sandors:piano technic
If I remember correctly, Sandor wrote to the effect that "the fingers should be independent...from one another. Not from the hand."
"Lifting one finger as high as you can and tap the key as hard as you can" is exactly how I was taught, and is widely accepted as one of the chief methods for building finger independence.
What does raise concerns is his insistence to keep doing it even if you have pain and tension. Did he really say that??
Opus Maximus -So was I taught to lift fingers high. But were you taught to hold down
the idle fingers? If I interpret the OP correctly, that is what his teacher recommended. It sounds very dangerous.
4. technic of finger independence: put your fingers on c-g
elevate only one finger as high as you can even with pain and tension
then tap the key as hard as you can
