[pianotech] Yamaha Spinet

[Roger@Integra.net]

Aart & Wim,
Also, one way to check if the piano, or the tuner is the cause of the "piano going out of tune", is to check the unisons. If unisons are going out, the tuner is most likely culprit. Just another physical aspect of the piano you'll try to explain to your customer.

  When you say long time customer, how long have you been tuning for him?  Has there always been a problem with the piano going out of tune within a couple of weeks after you tune it? Are you making those return calls free of charge? 

  You need to convey to him that there is nothing wrong with your tuning, and there is nothing wrong with the piano. The reason the piano goes out of tune is because of humidity changes, especially since there is no climate control in the house. So if he wants to piano to stay in tune, it just needs to be tuned more than twice a year. If he can't accept that, tell him to find another tuner.

Hi, 

Not sure if the list is still up, However i have a long time customer, who is a 
professional jazz Bass player.
He has a Yamaha 1970's  spinet tuned to A=440.  He uses the piano for rehearsals 
with his band and writing/arranging.
He tunes it twice a year May/June and December.
No AC in small city row house outside NYC. Summer is very hot and humid.
The piano fluctuates between - 20c in the winter and + 12c in the Summer.
I Tuned it  two week ago ( Lots of rain and high Humidity ) and as usual the 
piano was 12c sharp.
I tuned it to A=441 and he called yesterday saying that the piano is out of tune 
in the bass up to third octave.
This is the third call back I've had with this customer in two years. The pins 
are ok and I have tapped a few in over the last years.
I've advised him that maybe this piano has seen better days and he should get a 
better piano with a Dammp Chaser.
He and his budget say no. However I think his KB Player is expecting more form 
this piano then it can deliver.

I would appreciate some insight as to the pitch differential. Possibly the 
soundboard is expanding and contracting with the seasons?

Any thoughts on this?

Thanks,
