Keeping A440

< What could be causing such a drop?>


That's assuming the pinao(s) in question were tuned to A440; they may have 
been tuned flat, for whatever reason; maybe sheer laziness! Unforgiveable, 
but certainly possible. If they were new or newer pianos, than excess 
stretching of strings could be part of the reason,as well as humidity 
consitenly below 45%, causing the soundboard  lose moisture,(and crown) thus 
lowering string tension.

Greetings,

              I have a new customer who is head of a music department. 
Claims
she gets all the pianos tuned 3 times a year: All newer (1980+ -) Yamahas. 
One
is a grand C7.  I found them all around 8 cycles flat!  I find this 
difficult
to fathom. Yet the tuner's card is inside the piano with all the dates
written on it.


               I am really having a hard time believing that these pianos 
were
actually brought up to pitch at each tuning. I own a Yamaha. They hold a
tuning (In my home anyway). The pianos are only used about 10 hours a week 
more
than a residence. What could be causing such a drop?
