Kawai piano needs orthodonture

[Joe And Penny Goss]

Tom,
There are most likely two issues here.
The fire place for the tuning and either mice or moth damage to the felt
punchings or foreign matter under the keys at the balance rail.
This piano does not have a chance to stay in tune living in the same room
with a wood stove that burns logs ( a pellet stove would be another matter
as the heat from them can be controled.
Pianos and wood stoves are not a good mix!
Even if one placed a tea pot on the stove to give off steam it will not be a
controled enviorment that the instrument needs.
