I don't think the authors were clear enough what they meant by "vertical" or "transverse" or whatever. I think when Weibreich says "The vertical motion of the soundboard turns out to have much more 'give' than the horizontal motion" I think he means that the board is flexible in an up-and-down way (for a grand piano) but not in the side-to-side way. So I think it agrees with the other article. That's also consistent with those other articles from Perdue. One of them said something about the horizontal motions not having been studied, and they implied they didn't think they were the most important motions. Charles
