What's your opinion on that?
First, I think if there is the possibility to choose between letting fall down the finger on the key or jumping off the key instead, the latter possibility has some advantages to me bside the (questionable?) different timbre:
1. since the finger is already on the key before pressing, the probability for slips is less than the first method
2. the control of tone color (loudness) is much better since the degree how strong to jump off can be controled better compared to the fall down method
3. For the follow-up of the notes it is often more ergonomic to jump off a key instead to rest there because on jumps earlier to the next note that way.
This jump-off method is of course only possible if one does not need to hold the notes without sustain pedal.
But the topic question remains whether the tone of same loudness differs if played by a longer fall-down way in opposite to very short way but strong acceleration. I must confess, my ears are probably not sharp enough to safely hear the difference. But my current teacher is very bold in that, also a intermediate teacher I had, insisted in that the tone color (rich full sound compared to harsh sound) is different.
