[CAUT] Advice for achieving stability sooner?

[Ed Foote]

 Inre 40 cent pitch raises, Diane asks: 


I'm considering doing less careful pitch raises, but doing two of them before I 
try to tune.  Have also wondered about tapping strings on bridges.


 

 There is no need to be careful, at all, about raising a new piano 40 cents. you will need to be going 10 cents over 440.  I might even shoot for 441 or 442 on the first pass. (if they have been used for a year at 430, the small difference won't matter much. 
     The first time through, you are actually chipping.  I would get through them in maybe 20 minutes, just getting them near 440.  It doesn't matter if you are 10 cents off on each string, as long as the same number of them are sharp as flat!   Go fast, get the tension in the structure, and then tune. 
  I would raise all of them before I tuned any.  Then go back and tune. 
Regars,
