Has the customer complained about the tone of the piano? Are you =
trying to correct a problem from your viewpoint or hers? The voice of a =
piano is a subjective thing, and though you may find it objectionable, =
does your customer? =20
If so, try this formula from Baldwin: "A mixture of 25% water and =
75% methanol can be applied to the hammers to produce a mellower or =
softer tone. Care should be taken not to apply to stapled areas. The =
solution can be applied to the shoulders for moderate changes or to the =
strike point for more severe changes. It is recommended in most cases =
not to apply the solution to the top octave and lowest octave since =
these areas usually require more tone accentuation to be musically =
pleasing. It takes about 20-30 minutes for the solution to work. Fine =
voicing can then be performed with shallow needling to the hammers as =
needed to provide a consistent note to note tone."=20
This does work.

Subject: old Lowrey console
List,
I just got back from tuning a friends piano which is an old Lowrey =
Console (Charles Fredrick Stein). This was my third time tuning it in =
the past 12 months. It holds the tuning quite well, but the tone is a =
very ugly, schreeking, bright nasty sound that I can hardly stand while =
I tune it. She gives piano lessons every week on it and I can't =
understand how it doesn't drive her nuts. I have tried before to shape, =
needle, and soften the hammers to even out the tone a bit, but nothing I =
do seems to bring down the schreekiness. And to add on top of this, it =
sits on a hardwood floor which makes it echo throughout the house.
Is there an easy/short fix to this problem shy of replacing the =
hammers that anyone here has found?
