Hi Charles, 2 cents change for a concert tuning on any note. More than that and it is a pitch correction situation. An adapative overpull chart such as is used by Reyburn Cyber tuner can give domestic tunings for as much as a 10 cent pitch correction. It won't be terribly stable but it will be useable. If A4 were ten cents flat and RCT was used on a "unisons as you go" basis it would probably over shoot on A4 by about 4 cents by the time you got back to A4. Much of this pitch drop is due to the metal plate flexing. At 01:05 AM 01/09/2001 -0500, you wrote: >3) For a flat piano, how flat must it be in order for it to need a pitch >raise?
