Richard: On the contrary, I have lots of confidence in the engineers and physicists you mention. However, as far as we can tell none of them have written anything about this current discussion i.e. which moves first, the bridge or the sounding board (the chicken or the egg). Quotes from these people about other things does little but try to borrow their credibility. Until someone attaches accelerometers to bridge and sounding board of a real-world piano this discussion will continue ad infinitum. The "winners" and "losers" will be judged by readers as to the number of off-topic quotes or the writing style. dave *********** REPLY SEPARATOR *********** On 1/5/2002 at 4:50 PM Richard Brekne wrote: >"David M.
