Good evening, today my piano, an old three-quarter grand Kaps restored 15 years ago, started giving me this problem... when I play C, the B also goes down, whereas if I play B, the C does not go down... what happened?

Hypothesis: It could be that some of the keyboard weights have oxidized and swollen, and if they are positioned at the same point as the key, they touch each other. Check. Paolo

THANK YOU, in effect there was a point of friction that was resolved when I forced the key's "bottom" a little bit

When we press a key, it doesn't just move vertically, but also laterally.

If the key felts (gaskets) were very worn, it could also happen that the descending key comes into contact with the adjacent one, pulling it down with it.

Thank you Paolo.

In fact, even some of my clients say that I am excessively ...fussy!!

That's just how I am, I like to see things from more angles and aim for the highest quality possible.
