the fifths are slightly flat, meaning a little narrower. However, in some pianos and in some areas of the keyboard, they can be almost correct
Regarding the dampers, at this point, if it is heard along with the note, it depends on the hammer's striking point and the damper's prevailing damping point.
It could also be a problem with the hammer voicing. It could also depend on the string (the straightness of the strings should be checked). It could depend on a displacement of the string on the bridge (strike the string with a brass wedge at the bridge location)
The technician will check
Perfect. So in my case, where in the DO4 - SOL4 interval I hear about 3 beats every 5 seconds, should that be okay?
There are various things I need to have fixed on the action, as well as a proper tuning. I am from Amalfi and I purchased my piano from Santarpino of Scafati. I was fortunate enough to have my piano tuned by Aldo Santarpino until about ten years ago (I don't know if anyone here on the forum knows him). I assure you that it was a pleasure to play the piano after his intervention. Unfortunately, Aldo passed away a few years ago and no maintenance has been done to the piano for about ten years. In my area, I don't know anyone who does this wonderful profession (if anyone has any advice on whom to turn to, it would give me great pleasure).
Furthermore, the current quarantine situation makes things even more difficult and therefore, at least for the moment, it would be impossible to have someone come over.
I need to attempt some "home" recordings and so I looked for a DIY solution. That is why I asked for your advice, hoping to manage to resolve it at least in part.
Anyway, if I press the key very gently, the hammer hits the strings exactly in the 3 indentations it had previously before I disassembled the action, so I don't think that's it (since before my intervention - DAMN IT - I didn't notice this resonance problem)
I mean the segment where the damping acts. But I believe it is a matter of alignment. At a distance, one can no longer do more. Reviewing the photos, I notice what looks like a small spot of glue on one of the dampers in the lower part. Exactly the sixth one after the wedge-shaped ones. If that were the case, it could be that hardening causing the noise. Check it!
test to try: play A3 loudly and stop the three strings by hand with a piece of felt or something else,
if the annoying harmonics are dampened immediately--> it is the A3, se they are not dampened and are generated in another spot, another A or a fifth or a fourth, to be searched for... towards the bass!
or perhaps, maybe just a couple of weeks are enough, without touching anything,
---> by playing you could settle some felt in its new position... a bit out of place.

Hi Gia,
i performed the test you suggested and I confirm that it is indeed the A3 generating the harmonic. In fact, as a "counter-test," if I play A4 loudly I still hear the harmonic (even if less evident). By stopping the A3 strings and playing A4, I no longer hear it.

Hi Paolo,
effectively, the damping you indicated to me is indeed that of the A3!
In the event of hardened felt due to a glue stain or something else, is it necessary to intervene by changing the felt, or is it possible to restore it somehow?
If you can, using a very small and sharp cutter, remove that little piece of felt. If you can't, send me the exact dimensions of the small piece and I'll send it to you in an envelope, okay! I have to see if I still have it, though! Anyway, try to remove the glue; even if a little bit of felt comes off, it doesn't matter!
