odd sounding notes at keyboard - deception

pseudonym58

I can't be the only one to have experienced this:
I'm seated at the piano (in this case a Yamaha C2), and a note or two here and there sounds different from its immediate neighbors. Perhaps a bit duller, or with an unusual overtone, or even a more pronounced noise of the action on that particular note.
I used to get a bit concerned about it thinking that I would have to ask the technician to take a look at it - assuming that it was still present when the technician was next available for a tuning (not necessarily the case).
More recently I've discovered that the anomaly can be extremely localized, and highly dependent on where I'm sitting in relation to the piano. Often I can just stand up and play the same note and hear nothing odd or different about it whatsoever.
So I just mention that here, in case someone has had a similar experience.

pseudonym58 Are those key in the lower register? When you stand up, your ear is at a different position. The fact that sound perception changes relative to listening location makes me wonder if room acoustics is coming into play.

iternabe Various different places, it depends on the day. One thing that seems pretty uniform is the F, F# and G about an octave and a half above middle C seem a bit subdued. But as I mentioned, all I have to do is stand up and the difference between those notes and the notes around them disappears.
I figure we have enough things to worry about nowadays, I'm happy to set these things aside! 😆
