Good morning, about a month ago I tuned the new C1x piano (which had been delivered to me in February at A=444) to 440, trying to obtain the beats between the 5ths and 4ths and all in all I liked my tuning very much, and I still do. The piano is well-intoned, even when playing jazz chords they sound nicely "straight."
The problem, however, is that the strings "have conspired to spite me" and now the tuning has remained stable, but my A has gone to 438Hz.
If I had made a mistake, I suppose the strings "wouldn't conspire" to go out of tune in the same way "hoping I wouldn't notice"...
I'm joking a bit about it but the thing annoys me.
If I record with backing tracks I have to raise the piano, no big deal, but next time, should I keep it 1 HZ higher?
So, I realize that the 444 issue has diverted attention from the core of the subject and I am trying to explain myself better.
The piano was delivered to me in February (and not March, I checked) at 444 "because Yamaha does this, don't worry it will drop later. Only tune the out-of-tune notes, but don't bring it to 440, wait for it to go down on its own", this is what the shopkeeper told me.
I waited patiently, and for the first 2 months it stayed there, then (perhaps due to turning off the heating) it began to drop. When it reached around 440 on its own, I adjusted it, observing the beats between the E's, trying to perform a good tuning.
The core of the subject is that it then dropped even further, but without going out of tune at all; that is, all the strings lost that % in equal measure.
That's all, I was wondering if this had happened to anyone else. With my other piano, an upright, I was checking it because it was going out of tune and consequently I noticed that it had also dropped, but the strings were going out of tune. This one, however, lost those 2 or 3 hertz but remained perfect.
