Befana Tuning

Undoubtedly these fluctuations in temperature and relative humidity only serve to negatively affect the tuning. It could also depend on the stability of the pedals. Then it must be said that some designs are very pushed, if that is indeed the case. That is to say, I mean that some brands, on certain upright and grand piano models, push the length-to-gauge calculation of the strings to the limit in order to increase sound power. This results in thicker strings becoming more inharmonic and less precisely tunable relative to their length. One notices this when, while tuning, it remains quite difficult to hold the strings steady, as they tend to go out of tune with the slightest movement. This causes a small movement of the pedal or a minimal movement of the board to correspond to considerable detuning. And this is very evident on unisons, especially in the mid, high, and super-high ranges. Of course, a half-tone detuning almost always corresponds to a significant movement of the pedal, which, perhaps, in this case, did not have good stability and/or had not been "set" properly.

I forgot to say that years ago, on the ankle of the F, I had already practiced a'impiallacciatura. But what is meant by "stopping well"?

......So it was a bit slow.... Stopping well means that the tuner must clearly feel under the key when the bridge rotates or twists. The bridge stops when it is no longer subject to the pressure and support movements of the key. The older the piano, the more appropriate it is to look for a "support point" for the bridge on the hole, so that it is more stable under the tension of the stressed string.

Thank you Maestro, always kind and clear.
