Most people that claim that they or other family members have this trait are not accurate. What percentage of these people would be able to distinguish between two freshly tuned, similar pianos one at 440 and the other at 443. Especially if they would hear each after a period of time where they wouldn't have a fresh reference in their head.</DIV> <DIV> </DIV> <DIV>Byron</DIV> <BLOCKQUOTE dir=ltr style="MARGIN-RIGHT: 0px"> <DIV></DIV> <DIV class=OutlookMessageHeader lang=en-us dir=ltr align=left>-----Original Message----- From: David Ilvedson [mailto:ilvey@sbcglobal.net] Sent: July 26, 2006 7:57 AM To: dnereson@4dv.net; pianotech@ptg.org Subject: RE: A 435 or A 440 ? </DIV>5 beats per second?...if 442 is about 8 cents sharp, 438 would be about 8 cents flat and 435 getting close to 20 cents flat...that seems like a pretty hefty difference...I'd think it was noticeable to a 440 perfect pitcher...
