..stability issue..

[Phil Bondi]

Good Morning.

There are 2 Baldwin "R"'s in a restaurant that I have been trying to
maintain as a customer..frankly, I am getting frustrated with the complaints
that they won't stay in tune.

I have:

seated all strings.
beat the heck out of all strings while tuning.
added DC to both.
tried to educate the player..some people just don't want to listen or hear
what's being said..he is not a 'hard' player.

..still the same complaints..one piano is being played 6 nights a week while
the other is used sparingly..it is the complaint that Piano#1 goes out of
tune within a week of me being there and Piano#2 lasts 2 weeks..now please
understand that 'out of tune' means, to this person, that some unisons are
starting to drift.

Both pianos are scheduled to be tuned every 2 months.

The restaurant's climate is not ideal, and that is why I suggested the DC
for both..but it doesn't seem to be adding any stability to my work.

I have questioned my own 'technique'..but only with this customer, which
makes me think that it's not my technique preventing these pianos from
staying in tune since I don't have this complaint with any other customers
that tune as frequently as this one does.

Does anyone have a suggestion for improved stability, based on what's been
said here?

At wits end,
Rook
