birdcage pitch?

[Farrell]

That´s pretty unusual. Is it possible that there is a relation between the stability and these 7 passes?

My guess is not. I raised the pitch of an old upright Kimball more than 100 cents (don't remember exactly how much) about six years ago. One year ago I returned to tune it again (only needs tuning every 5 years) and it was right up to A440. I think a big ol' flat, dead soundboard has more to do with it than how many passes one uses to get a piano up to pitch.

  Terry,
   
  yes, probably you are right. But I was afraid of breaking strings and I had the hope that the the likelyhood of damage is smaller. Of course there are pianos where I have not so great doubts. Last week I did such a pitch raise without any problems (in field service), but that piano was built 1935 and not 1900.
   
  And yes, 6 or 7 passes are a lot of work. On the other hand: the tuning was still stable after 4 month and only 1.5 to 2 cents flat in all areas. That´s pretty unusual. Is it possible that there is a relation between the stability and these 7 passes?
