Well, do you agree with the following statement? Is it "加速曲线" or purely the speed that the hammer strike the string that determine the tone? "音色问题 钢琴音色变化无穷,在于从压键至发出声音之间加速曲线的不同。压键之后快速加速会 产生明亮的音色,压键之后缓慢加速发出的声音较柔和。压键后没有加速就会产生粗硬 的声音(这是没学过琴弹出来声音不对头的原因) 触键技巧, 钢琴有多种触键技巧 包括手臂用力的方式,手腕如何放松,手指的曲度,都是为了产 生不同的加速曲线,使钢琴发出无穷音色变化而来的。 电钢完全没有这个接收加速曲线的机制,它只接收一个恒定的速度,一个速度配合一个 音量层级。"

Well, do you agree with the following statement in his original words? Is it "加速曲线" or purely the speed that the hammer strike the string that determine the tone timbre? I am not arguing whether there will be difference. I am arguing his explanation.

chinese restaurants just stink. you go to the back street behind any of them
, it stinks right there outside the kitchen where the chefs smoke and chat.
can't blame the sewage system. those people just have a very low bar for hyg

Why? That paper is simply aimed to study this claim "They establish and refine various kinds of accelerating the keys in order to obtain finest timbral shades so that it might be hard for them to believe that piano timbre might be expressed by a single physical parameter" 我们物理学家本来就没有说摁键力度不影响音色。我们只是认为取决音色的唯一因素就 是锤子敲弦的速度。而不是那些故弄玄虚的加速度。这篇paper研究的就是这。你说说 那儿胡扯?

打人造成的伤害只取决于力度和受力面积,所以用兰花指或者鼻子或者拳头打人是没区 别的。
