Greetings; Gina writes; >>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? The sound transmission path is the important aspect of the continual bridge. Remember, sound travels a lot better with the grain. Now, if you will take a soundboard steel, and pass it under the "unstrung" section, I think you will find that there are acoustic dowels joining the soundboard and bridge. These are the dowels that have the large wooden nuts that are visible on the underside of the soundboard on the Steinways. I am not so sure about the Yamaha. There is only one bridge on these models, and a gap between the bridge and soundboard does not alter the acoustical linkage formed between the treble and bass sections.
