Try to kept lights down, and stabilize the temperature as much as possible. I don't think it's your tuning technique at all- I've found these instruments to be less stable than harpsichords.</DIV><DIV>Good luck</DIV><DIV>Steve Kabat<BR></DIV><FONT color=#990099>-----caut-bounces@ptg.org wrote: -----<BR><BR></FONT><blockquote style="PADDING-RIGHT: 0px; PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #000000 2px solid; MARGIN-RIGHT: 0px">To: "'College and University Technicians'" <caut@ptg.org><BR>From: Marcel Carey <mcpiano@videotron.ca><BR>Sent by: caut-bounces@ptg.org<BR>Date: 11/11/2006 08:22AM<BR>Subject: [CAUT] RE : Fortepiano stability<BR><BR><DIV><SPAN class=218342013-11112006><FONT face="Default Sans Serif,Verdana,Arial,Helvetica,sans-serif" color=#0000ff size=2>Hi Geoff, </FONT></SPAN></DIV><DIV><SPAN class=218342013-11112006><FONT face="Default Sans Serif,Verdana,Arial,Helvetica,sans-serif" color=#0000ff size=2></FONT></SPAN> </DIV><DIV><SPAN class=218342013-11112006><FONT face="Default Sans Serif,Verdana,Arial,Helvetica,sans-serif" color=#0000ff size=2>I'm no expert, but I find that some instruments don't respond so well to hard blows. If you find that your unisons are going sharp, you may be hitting too hard and creating stability problems. Or is it just the temperature change... This is a major factor with these instruments. </FONT></SPAN></DIV><DIV><SPAN class=218342013-11112006><FONT face="Default Sans Serif,Verdana,Arial,Helvetica,sans-serif" color=#0000ff size=2></FONT></SPAN> </DIV><DIV><SPAN class=218342013-11112006><FONT face="Default Sans Serif,Verdana,Arial,Helvetica,sans-serif" color=#0000ff size=2>Marcel Carey, RPT </FONT></SPAN></DIV><DIV><SPAN class=218342013-11112006><FONT face="Default Sans Serif,Verdana,Arial,Helvetica,sans-serif" color=#0000ff size=2>Sherbrooke, QC </FONT></SPAN></DIV><BLOCKQUOTE dir=ltr style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #0000ff 2px solid; MARGIN-RIGHT: 0px"><DIV></DIV><DIV class=OutlookMessageHeader lang=fr dir=ltr align=left><FONT face=Tahoma size=2>-----Message d'origine----- <BR><B>De : </B>caut-bounces@ptg.org [mailto:caut-bounces@ptg.org] <B>De la part de </B>Geoffrey Pollard <BR><B>Envoyé : </B>11 novembre 2006 07:37 <BR><B>À : </B>College and University Technicians <BR><B>Objet : </B>[CAUT] Fortepiano stability <BR><BR></FONT></DIV><P><FONT size=2>Hi all from Oz, <BR><BR>I'm tuning 3 fortepianos for the Mozart triple piano concerto series this week and next, here in Sydney, for the leading baroque orchestra. Have just staggered home from Sat night after Friday night's first concert. Tuning stability was not good - and I am looking for any help from fellow CAUTs on techniques to nail tunings that will last more than one movement. I have about 2 hours pre-concert for tuning - 40 mins each. I'm hitting hard, and the 3 are becoming more obedient, but the arrival of 1.500 audience seems to unsettle them! Unison and octave drift. Any advice from fortepiano gurus out there? <BR><BR>Thanks, <BR>Geoff Pollard <BR>Sydney Conservatorium of Music <BR>University of Sydney <BR><BR></FONT></P></BLOCKQUOTE></blockquote><br></FONT>
