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.

The treble bridge extends under the plate and connects with the bass bridge. dave >>
