I know about climatic changes that effect the soundboard. This causes the who piano, or at least whole sections to go out of tune. I can accept that. But I pride myself on setting the string and the pin. I am a pounder. On new pianos, (at least new to me), and especially concert instruments. I beat the daylights out the notes to get them to stabilize. But there are still strings that go out. That is why we tune concert instruments numerous times, with strings still going out. </DIV> <DIV> </DIV> <DIV>I tune a D for a church once a month. I pound until my fingers hurt but I leave the string with the lights standing absolutely still. But every time I tune it, the piano is "in tune" in that it hasn't changed pitch over all, but there are at least 2 dozen strings that have "slipped." They are 2 or 3 cents off. I'm not talking notes, I am talking string. The right string of one note is 3 cents low, or the left string of another note is 2 cents flat. </DIV> <DIV> </DIV> <DIV>Why is that? Why do just these strings go out, and not the other ones? Am I still not pounding hard enough, or is the combination of slight variations in temperature, combined with strings that maybe weren't set right, causing this? Inquiring minds want to know.</DIV> <DIV> </DIV> <DIV>Wim</DIV> <DIV><FONT lang=0 face=Arial size=2 PTSIZE="10" FAMILY="SANSSERIF">Willem Blees, RPT<BR>Piano Technician<BR>School of Music<BR>University of Alabama</FONT></DIV></BLOCKQUOTE></DIV></BLOCKQUOTE><BR><BR>Vince Mrykalo<br>University of Utah<p><hr size=1><font face=arial size=-1>Do you Yahoo!?<br> Yahoo!
