What is tuning?

The answer is: it is the intervention that harmonizes the hammer regions and allows it to generate a proper forte as well as a pianissimo with ease of touch. The closer the voicing is to the pianist's "intentions," the more effective it is. Naturally, before voicing, one must verify the centering of the hammers and the planarity of the strings relative to the apex of each hammer. Shaving does not always improve timbre. It is, however, appropriate to voice the hammers again after shaving. The entire hammer, after shaving, becomes smaller and all the felt zones are reduced. The proportion between the compressed part and the expanded part changes. I am in favor of delaying shaving as long as possible or even avoiding it altogether. It is extremely important to preserve the original shape of the hammers, something that, especially in the high notes, is not always possible. Many technicians thus tend to round off the high notes, not having much felt available and having deep grooves. NOTHING IS MORE HARMFUL. Apparently and momentarily the sound will seem more compact, but shortly and irreversibly the high and mid-high notes will become unpleasant and devoid of sonic range. In fact, besides making the striking point equal to a segment (thus putting dissonant harmonics into vibration that will not be eliminated precisely because of the indeterminacy of the striking point), it will happen that the hammer, not having an adequate shape, will not react in all its zones as it should, even with exasperated and perhaps useless voicing: This is my opinion

We students of the "Paolo Ferrarelli" school completely agree.
