ChenYN Piano Tuner 陳師傅調音-象牙琴鍵的修復（紐約）

今天的維修項目是象牙琴鍵著實讓我驚嘆不已，因為現在使用象牙做琴鍵的琴是越來越少了，特別是60，70年代之後生產的琴都很少象牙琴鍵了。

今天遇到的象牙琴鍵各項測試指標都非常吻合（The main giveaway of ivory keys is that they tend to have a line where the stem and the key top join running through the keys at the base of the black keys.）其中紋路和柔滑、吸汗，等都是其他材質鍵盤所不具備的，也就是說防滑象牙是制琴鍵最好的材料。許多老牌鋼琴家都是十分青睞象牙鍵盤滴，表示在象牙鍵上演奏的感覺與用塑料鍵製作的感覺不同。（Pianists have expressed that playing on ivory keys feels different from those made with plastic keys.）

The main giveaway of ivory keys is that they tend to have a line where the stem and the key top join running through the keys at the base of the black keys.
