This is a great reply and drifting toward the answer if there is one, if there was ever a clear question. I find it questionable, however, to say, "I see no reason that the piano won’t stay in tune for any shorter a period of time than one not requiring a pitch correction". This seems totally counterintuitive and is one of the reasons for the original query. P In a message dated 8/28/2009 10:43:46 P.M.

The bottom line is that the more you go over the piano the more likely you are to catch and correct any stubborn segments. The tendency for the segments to be stubborn will be influenced by the piano’s design, counterbearing angles, string condition, etc.. -------------- next part -------------- An HTML attachment was scrubbed...
