curved church floors

[Andrew and Rebeca Anderson]

It can be rather enlightening regarding your technique to push down 
the damper pedal and play all the keys loudly (test blows) with your 
flat hands several times and then check stability.  Made me change my 
technique and you can do that to a piano I have tuned and have 
nothing move.  Moving the piano doesn't really bother them 
either.  Climate change does though that is a different issue...

I recommend doing that to pianos you are tuning the first time and 
especially after the first pitch-raise pass.  That extra loud 
vibration going on throughout the board can help distribute some 
tension back behind the bridge.  Especially on older rusty pianos you 
may find that is will help do that.  The other is to rub each string 
with a maple hammer shank or better, a notched brass rod pulling away 
from the bridge.  Don't push down so hard up close to the bridge that 
you damage the bridge-capping.
