Piano needs time to breath in/out moisture and then changes it's pitch gradually. earlier summer,this piano had started to raise it's pitch,but not raise too much; earlier winter,this piano has started to lower it's pitch,but not lower too much yet. That's my guess. Baoli PS:the cooler temperature can raise the pitch a little bit. --- Ron Koval <drwoodwind@hotmail.com> wrote: > New one for me: > > Here in the midwest, it's common to see all the > pianos tuned over the summer > needing pitch raises now, as the heat has been on > for awhile and the > humidity has dropped. > > Petrof 7' in a church, I'm reasonably sure that I'm > the last one that tuned > it on 6/8, where the humidity was around 45%.
