I've postedthis puzzler on both lists and the two groups are at about the same point (ifyou remove Ed Sutton's formidable contributions from the mix, anyway). Toreview for one and all, the instrument in question is a mainstream grand pianoof relatively recent vintage. The answer is neither of the first twothings that came to the minds of so many of us, cheating jack and too-closeback check (sounds like a country music duo, don't it?). Nor is it abroken keystick or any of Ed Sutton's deeper speculations (on the CAUT list)about flexing balance rails and broken keybeds (man, Ed, you have seen some prettyinteresting stuff!). Also, it is not Catastrophic ActionFailure--remember, it is not a repeated note thing--or a foreign object. Time for more information: There are two problem notes, one in the bass and one in the lower treble. The worse one is in the bass, probably because of the greater mass of thehammer (compared to the other one). When these notes won't play on a hardblow, one of their neighboring hammers moves slightly.
