Dave(s),

My personal piano is a Yamaha C7 B. It has a "continual" bridge. After
reading your posts this morning, I took my trusty flashlight, removed all the
junk, excuse me the  terminology properly would be removed the errata storage
items, from the lid.

At the point where the lower tenor bridge curves under and forms the bass
bridge, there is no contact with the curved, unstrung, bridge section and the
soundboard. So, in effect, there is one structure but two, distinctly
seperate bridges. Or, to put it another way two distinctly seperate areas of
transmission on this one piece structure.
  This being the case, are there not in fact "two" bridges in actuality?
 Steinway has this arrangement, as well as many other past and present
Marques.  I believe that an area of unstrung bridge curving around and
forming another part of the bridge, while contacting the sounding board,
would in effect act as a damper on the movement of the board.

 Steinway "Ds" and "Bs" have one continuous bridge.  Look closely next
 time you see one.  The treble bridge extends under the plate and
 connects with the bass bridge.
