Stability problem

Hello everyone,
A customer who is a piano teacher has a D H Baldwin grd C 152 made about
1990.  When she called me to tune the first time 9/97 she mentioned that
the piano seemed to go out of tune quickly.   When she called me early
January 98 to tune the piano again, she said the piano had sounded fine for
about 3 months then went out of tune so badly she counldn't stand it. I
tuned it for her this morning 1/10/98 which was about four months after the
first tuning.  The piano had gone way out of tune in the middle - the
unisons were way out.  A3 had dropped from +1 cent (9/97) to -23 cents
1/10/98.  Quite a bit for a seven year old piano that according to the
customer, had been tuned about every 5 months from the time it was new.

The pin block seemed a bit spongy when I tuned 9/97.  Today the pins moved
more crisply but I felt that the piano had gotten a good solid tuning  each
time.  She also has an old Wheelock grand in the same room which she uses
to play duets with her students.  It seems to stay much more in-tune.

Has anyone had tuning problems with the DH Baldwin model C 152?
I'm trying to determine if the piano is just in a bad environment and needs
humidity control, or if the tuning problems are structural or in the nature
of this model.  The soundboard and bridges look fine.

Any information appreciated.  Rolland Miller rmiller@en.com
