众所周知,决定钢琴质量的二大要素是钢琴音质和弹奏品质。前者决定于弦列共鸣系统的音响效果,后者决定于击弦机的动作机能。本文不论钢琴的音质,仅浅谈击弦机灵敏度的有关因素。根据质量要求,击弦机必须高度灵敏:如每秒钟按键8～12次,要发出清晰的8～12响声音;按键力度的大小不同时,要能在音量上反映出微细的差异;……因此,这套钢琴击弦机既定构造曾被誉为18世纪机械结构的奇迹。要充分体现出它灵敏
It is well known that the two major factors determining the quality of a piano are piano sound quality and playing quality. The former depends on the sound system of the string resonance system, the latter depends on the action of the action machine. This article regardless of the piano’s sound quality, only talk about the sensitivity of the action-related factors. According to the quality requirements, the striker must be highly sensitive: If the button is pressed 8 ~ 12 times per second, it should give a clear 8 ~ 12 ring sound; when the intensity of the key is different, it can reflect the slight difference in the volume ... ... Therefore, the pianist was designed to create a miracle that once was hailed as a mechanical structure of the 18th century. To fully reflect its sensitivity
