[CAUT] pinning

[Richard Brekne]

Hi David

I know there are several opinions about how pinning can affect tone 
and/or if it does at all to begin with but my experience tells me that 
as solid a pinning as is possible without compromising the ability of 
the action to play and repeat quickly is a precept for good voicing and 
good projection. Whether it is because the tighter pining causes a more 
solid path and impact moment, and less dispersion of impact energy back 
through the system or not... I really dont know.  I think like many such 
subjects, the actual physics is something we do a lot of guessing at but 
really dont <<know>> much about.  That said... the difference in sound 
and projection is real enough and its one of the things I do very early 
on in any full voicing/regulation beef up I do on an instrument. Like 
hammer mating and unisons being in a level plane.

Cheers

    I have been having some interesting time with our Hamburg Steinway
    here at Stanford.  This is 9 years old.   I filed the hammers for
    the first time...I know, not heavy playing...but I repinned for the
    2nd time in a year.  Went from 4 grams to 2 grams or so...I decided
    to repin at 5 to 6 grams.   The tone is projecting (tone above the
    strings) to beat the band...the combination of careful filing and
    repinning has, imho, brought the piano back to it's new piano
    sound...I'd appreciate comment on center pinning/tone and concert
    instruments...
