Thanks >les bartlett > >________________________________________________________________ It is not in my experience that any 100 cent pitch raise is stable no matter how many hours you spend on it and irregardless of whether an ETD is used or not. I know others report stable tunings, but I find very consistantly that if I am doing such large pitch raises the piano is much more stable over the long term if I raise pitch and rough tune for play on one day, and come back a week or so later to do a fine tuning. I find very often that the piano has moved significantly in that time. And I find that the amount of movement varies greatly from piano to piano. This tells me that the stability of the instrument when pitch is so severly changed is basically unpredictable... so I like to simply come back a week later and make sure it sits good...
