哈哈！最近调音检查了一架施坦威（M）钢琴的状况，测试音律A-430赫兹低于A-440赫兹将近十个音分左右。调音完毕后写下一点感想侧记：
施坦威钢琴的调音给予技师最大的机会以变得有创造性，施坦威的声音应均衡而优美，并具有多种色彩。
贯穿键盘，无数演奏家包括音乐家以各种力量（演奏），低音、中音和高音都会得出不同的感受。重要的是，调音技师需要熟悉音乐家的需求，并能够就什么是每个钢琴所呈现的特质做出评估。
每架施坦威钢琴的（声音）色彩和功率范围都会有所不同。要使钢琴达到其顶峰而又不超越边缘通常会产生最佳效果。哈哈！调音师任重道远呀！
附（施坦威工厂检查程序）
1. 对所有的部件确认。(包括，对已损坏的配件做更换，或修理，修正)。
2. 对挂线系统的确认。
3. 对键盘的确认。(包括，琴键的后档键下尼，中档圆销钉孔，尼; 前档扁销钉孔，尼; 键高，键深确认)。
4. 榔头的形状，与弦的工作关系确认。
5. 键盘与机芯的联动工作确认。
6. 机芯的机件连联动确认。
7. 对钢琴的标准音高的确认，精调完成。
8. 对音效的确认，(包括，音量动态，音色的定位)。
Someone walking through the factory, following a single piano as it takes shape, could forget a basic fact: Every Steinway is made the same way, from the same materials, by the same workers. Yet every Steinway ends up being different from every other--not in appearance, perhaps, but in ways that are not easily put into words: colorations of sound, nuances of strength or delicacy, what many pianists call--here's that word again--personality. Some Steinways end up sounding small and mellow, which is fine for chamber music. Some are so big and muscular and percussive that a full-strength orchestra cannot drown them out. On some, the keys move with little effort. On others, the pianist's hands and arms get a workout.
