Regulate by feel (was : Bechstein grand spread dimension)

[Isaac OLEG]

Hello,

These are also visual impaired tuner's methods, there are many very
useful tricks to learn from then.  Knocking there and there, knowing
the good regulation by ear and feel.

I don't always think about it myself, but closing eyes is a good way
to come back to what you are doing if the feeling escape while tuning
or regulating.

Talking about the drop moment, at any price I will not delay the
contacts between regulating button or screws, this is robbing tactile
feedback, precision and control to the pianist. If the jack can brush
under the roller before letoff, then its position may be too far. I
always aim for one friction moment, then the hammer is the most
energetic.

And then the pianist can use its weight to play because he can trust
where the note will speak, using its weight instead of retaining it or
using articulation is giving him a fuller tone naturally.

There is a wedging effect between the roller, the top of the jack and
the lever when stopped by the screw that gives that catapult effect to
the note and that nice feeling of letoff + aftertouch.

When properly done the note can play pppp to FF in only its last half
of the dip.

Have nice pianos .


Regards

Isaac OLEG
