[pianotech] Pitch raising limit

[Joe Goss]

Hi, A lot will depend on the first pitch raise and how the piano reacts to it. I would expect with my SAT at least two major raises setting the first pitch to any page. On the  second pass  if the piano is still aprox 100 low the same page. On this pass I would also check the wound strings and raise only 12.5 measured at A2. Third pass should be within 15 cents.
Measure for page info ( stretch ) and tune, checking A2 again. It should be within 3 cents so no over pull.
For concert venue 4th tuning the next day.

  Greeting for the day List

  What is the pitch raising limit? How many cents can one pitch raise without ruining/overstretching the strings, eg (for lack of words)- Piano is 200 cents flat and your customer wants the piano to be tuned to A442. Is this a one pass pitch raise, and then tune or 3 pass pitch raise, how, what and why would you do?

  Please excuse the way I have asked the question/s.  I don't know how to ask it better, simpler, clearer. 

  Thank you,

  Regards
