Are you sure you were measuring precisely at the strike point? If you were measuring somewhat forward of the strike point, you would consistently get the results you describe. Usually, the diameter of the wire,the incline of the string, and the strike point are taken into account in calculating the counter bore for <SPAN id=""><SPAN id="">agraffes</SPAN></SPAN>, to achieve equal string heights at the strike point. It is also possible that the plate could have been set lower than intended in the design, causing the bridges to be planed lower for correct bearing, and thereby, inadvertently compromising the consistency of the string height at the strike point.</FONT></div> <div> </div> <div> <div>Frank Emerson</div> <div> </div> </div> </div> <div> </div> <BLOCKQUOTE style="PADDING-RIGHT: 0px; PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #000000 2px solid"> <div style="FONT: 10pt Arial">----- Original Message ----- </div> <div style="BACKGROUND: #e4e4e4; FONT: 10pt arial; font-color: black"><B>From:</B> <A title=reggaepass@aol.com href="mailto:reggaepass@aol.com"></A></div> <div style="FONT: 10pt arial"><B>To: </B><A title=pianotech@ptg.org href="mailto:pianotech@ptg.org">pianotech@ptg.org</A>;<A title=caut@ptg.org href="mailto:caut@ptg.org">caut@ptg.org</A></div> <div style="FONT: 10pt arial"><B>Sent:</B> 6/7/2007 12:59:12 PM </div> <div style="FONT: 10pt arial"><B>Subject:</B> string height</div> <div><br> </div> <FONT size=2>Hi Lists,<br> <br> We recently measured string heights on a Steinway B andÂ Yamaha <SPAN id=""><SPAN id="">G2</SPAN></SPAN>.Â An astute assistant noticed that on both pianos the highest note (pitch-wise) in the tenor was higher than the lowest note in the tenor (more than can be explained by the gradual decrease in wire diameters, were the <SPAN id=""><SPAN id="">agraffes</SPAN></SPAN> all level) and that the lowest note in the capo (pitch-wise) was higher than the highest note (<SPAN id=""><SPAN id=""><SPAN id=""><SPAN id="">C8</SPAN></SPAN></SPAN></SPAN>).Â Is it just a coincidence that we happen to measure two very different pianos with this same set-up, or is there an overarching design reason for this (making it a goal by design shared by many manufacturers)?<br> <br> Thanks,<br> <br> Alan <SPAN id=""><SPAN id=""><SPAN id=""><SPAN id="">Eder</SPAN></SPAN></SPAN></SPAN> <div class=AOLPromoFooter> <HR style="MARGIN-TOP: 10px"> AOL now offers free email to everyone.
