[pianotech] Further explanation: How long do unisons hold?

[Dean May]

Well your C3 examples are the perfect illustration- identical pianos tuned
at the same time. Unless you are stopping by the bar before tuning the
pianos that end up horrible, the stable pianos give proof that you are
giving a stable tuning. No outside influence I'm aware of will take a poor
tuning and make the unisons stable. But we know the converse is true:
outside influences can and do take a relatively solid tuning and destroy the
unisons.

That's what can be confusing. Some pianos, such as those that I tune on
cruise ships (Yamaha C3s) I see every two weeks. Some are pretty good after
that time and some are horrible. The other end of the spectrum is a lady who
has a Baldwin Hamilton (maybe 1970 or so) and the once per year that I see
it, I often start out - after an initial listen - wondering why she wants to
tune it - the darn thing is sooooooo stable.

 

Seems hard to judge.

A good check on yourself is to look at the pianos you regularly service.
When you find a lot of unisons still fairly decent after 6 to 12 months, pat
yourself on the back. You are doing a good job.

 

Some pianos are awful in that amount of time of course. I comfort myself
with the knowledge that lots of pianos I tune regularly are not. I know that
my tuning skill can produce a moderately stable tuning because I've seen
lots of these among my clientele. So for those that go awful, chock it up to
environmental/other issues.
