Article about bridge agraffes - function, types

[Byeway222 at aol.com]

Hello JD and list,
 
One of the advantages or spin-offs of the 'floating soundboard' is the  rock 
like stability of tuning.  I look after a couple of Stuarts and the  tuning 
stability is to die for.  Even after the flight from Australia, 3  days at the 
airport and the road journey to its destination, the  concert grand tuning was 
solid and at pitch.  I literally could not  even find a unison to tidy up.
 
But why do you need downbearing when, with agraffes, you can have a  thinner 
soundboard with ribs which only act to disperse vibrations.  If you  think 
about it, the traditional crowned soundboard construction is the  eventual kiss 
of death to the piano.
