The "two days without heat" were some weeks back. She has been playing harder than usual for the last several weeks. I just did two Kimball Grands and a Baldwin upright today which I also service regularly which were more than the "average" amount flat. Maybe it's just the big weather changes......... Thanks for observations. I'm amazed at how fast a piano can change. I did a Steinway D which was delivered to a local outdoor pavillion at 10:00 in the morning. When I tuned it at noon it was still in very good shape. After it had set outside all day, and three hours in the direct sun it was a disaster...... les -----Original Message----- From: caut-bounces@ptg.org [mailto:caut-bounces@ptg.org]On Behalf Of Ric Brekne Sent: Thursday, December 08, 2005 9:53 AM To: caut@ptg.org Subject: [CAUT] Petrof tuning Well... yes. But in my experience the kind of movement in the piano you describe usually takes more then a couple days of somewhat lower then usual RH. Could be the piano just <<gave in>> to the change. Still... 24 cents of movement on a stable instrument after two days of moderate (?) drop in RH ??.... stranger things have happened but..... I have to hang my hat on the doubtfull krage. Cheers RicB ------------ Previous tunings (every six months) never varied more than 5-7 cents. Houses here are central heat/air, and normally really locked down. Most never open windows. Could two days in relatively low humidity, with no heat or air, make that kind of difference? les _______________________________________________ caut list info: https://www.moypiano.com/resources/#archives
