I know ab= out 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, (a= t 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 s= till 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 ever= y time I tune it, the piano is "in tune" in that it hasn't changed pitch ove= r 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 stri= ng 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 variati= ons in temperature, combined with strings that maybe weren't set right, caus= ing this? Inquiring minds want to know.</DIV> <DIV> </DIV> <DIV>Wim</DIV> <DIV><FONT lang=0 face=Arial size=2 FAMILY="SANSSERIF" PTSIZE="10"= >Willem Blees, RPT<BR>Piano Technician<BR>School of Music<BR>University of A= labama</FONT></DIV></BODY></HTML>
