Good morning, a few years ago I bought a new Schimmel grand piano.
For some time now, I have noticed that when certain keys are pressed with enough intensity to generate a loud sound, in addition to hearing the sound of the note, I hear a woody noise-sound corresponding to the key. This happens when the key hits the bottom. In other words, when I play some keys loudly, besides hearing the sound of the note, I also hear the "sound" of the key.
This problem, which I can assure you is very annoying, actually arose after having the action regulated, which according to the technician had to be done. I had owned the piano for two years. I pointed this out to the aforementioned technician, who pretended nothing happened and said it was normal.
I don't think it is a matter of friction because all the keys are fluid and slide in the same way, however, I am not a technician.
I don't want to think it's the detachment of the hammer heads.
It could instead be poor adjustment of the frame supports. If they are screwed in too much, they could cause the front part of the frame to rise too high, resulting in a loss of contact with the soundboard on which it slides. During a strong strike, the gap causes "clattering between the frame and the soundboard" at the front, corresponding to the key depression.
Hello, I have an upright piano whose hammers were recently replaced.
My problem is this: when some keys are pressed softly, they do not have a complete depression, and I noticed that this can only be achieved by pressing the key again until it makes a click.
Could you help me understand what the problem is?
Thank you
Liliana

Hello Liliana,
if I understood the question correctly, when you depress the keys, you feel a click at the end of the key dip.
If this is the problem, the cause could be a poor regulation of the let-off mechanism.
In practice, that small gap between the top of the repetition lever and the leather located under the walnut felt might have been eliminated; if so, the lever has gone to "load" the hammers and over time has created a groove/notch on the walnut leather, causing a click at the bottom of the key dip.
If this is the case, ask your trusted technician to check the leather gasket of the hammer repetitions and subsequently intervene by adjusting the mechanism.
Attention !!!! It could also depend on the spoons that lift the dampers. These rest against a white felt which, if of poor quality, even after a short period of use, creates "a small hole" and the spoon gets stuck inside, causing a sensation of a "step" under the finger. It could be.
