Blind Pitch Raises

[ITUNEPIANO at aol.com]

A piano 100 cents flat won't be stable no matter how many pitch  
raises/tunings are done in a sitting.  It will still fall out of tune  within a few days 
as the piano acclimates to the increase in string  tension.  So, IMHO, it's a 
waste of time to try for a fine tuning on a  piano 100 cents flat.   By all 
means, pull it up to pitch in one  sitting, but tell the customer you need to 
return in two weeks.  By the  time you return, the piano would have settled, and 
a fine tuning will hold for a  reasonable time period.   On some spinets, 
often the return trip  requires a pitch raise.   I think those pianos that had 
regular  tunings early in life hold better after a 100 cent pitch raise - but how 
many  pianos get regular tunings?   Bob
