I like to get your opinions on a probably controversial thing: If one likes to have a certain pretty high volume (loudness) of a single note, one surely can do in two etreme ways (and all in between): a) the finger could be dropped down from a certain heigth on the key or b) the finger could be on the key and pressed down hard. Let's assume that we have produced a sound with same loudness with both ways. Do you think it has also the same timbre and sound color or not? It seems there are different opinions on that. My piano teacher treats me to play loud notes more with the b) approach instead the a) approach. Because the a) approach is considered to produce a more harsh sound instead a rounder tone with b). And I do think too meanwhile that there is indeed a difference, even if it is a very tiny one. But some may disagree and say, same volume = same timbre, regardless how it was produced? The online piano book from Chang tries to explain that this sound color differences may come because in b) the key is accelerated faster, so the hammer shank will be be bended, what influences the sound, especially for the deeper bass notes. However the book let it be uncertain whether the effect is really audible. What's your opinion on that?
