<html> <body> Ron, How long since the last tuning that it was 60 cents flat? <tt>The owner didn't know. </tt>More likely, it was strings rendering through the bridge over time after you had done the pitch raise and left the building. <tt>Yeah, but I work on other pianos that don't behave the same way.  Vladan may have something on the pin-block fitting issue.  It did tune up solid while I was there and going over a second time everything was still within 1/2 cent with a 5cent correction in one pass.  I'll look closely.  I've just noticed the same thing on a number of Baldwin grands and am looking for common denominators.
