<WBR>Jon<br> <br> A lot has to do with the quality of the piano. For good quality grands, I use the checks you do, or the two octave and a 7th. On less quality grands and most vertical pianos, I mostly listen to octaves and double octaves.  <br> <br> <div style="CLEAR: both">Willem (Wim) Blees, RPT<br> Piano Tuner/Technician<br> Honolulu, HI<br> 808-349-2943<br> www.bleespiano.com<br> Author of <br> The Business of Piano Tuning<br> available from Potter Press<br> www.pianotuning.com</div> <br> <br> -----Original Message-----<br> From: Jonathan Golding <jgmdpiano@gmail.com><br> To: pianotech@ptg.org<br> Sent: Thu, 17 Jul 2008 4:07 pm<br> Subject: question for aural tuners<br> <br> <div id=AOLMsgPart_2_3728323e-95c2-41f9-8376-54e772d5500a> <div dir=ltr>When tuning the last octave of the piano's bass section I would like to know people's opinions on how they get the best results. For me, I find this a tricky area to get consistently good results. Some bass strings sound dead whereas others are harsh sounding and some have lots of overtones. As well, each piano seems to have a different amount of stretch to take into consideration.  When tuning the last octave I usually check using the Maj 17th against the Maj 10th for approximate equal beating. When I play the octaves together harmonically I find that this leaves the last octave sounding too high to my ear. Any comments or suggestions? Any single partial for this area which could be helpful?<br> Thanks, Jon<br> </div> </div> <div id='u8CAB6C4B6E2425D-1614-4118' class='aol_ad_footer'><FONT style="color: black; font: normal 10pt ARIAL, SAN-SERIF;"><HR style="MARGIN-TOP: 10px">The Famous, the Infamous, the Lame - in your browser. <A title="http://toolbar.aol.com/tmz/download.html?NCID=aolcmp00050000000014" href="http://toolbar.aol.com/tmz/download.html?NCID=aolcmp00050000000014" target="_blank">Get the TMZ Toolbar Now</A>!</FONT> </div>
