Resonance

[David Ilvedson]

Also check with the shift pedal to see if, when shift engaged, it is now more like it's neighbors...

Hi Philippe.
 
One quick test would be to switch the Ax hammer with it's neighbour, the Bbx hammer, see what happens.  This way you will see if it is the hammer or not.  If not, we have one more mystery at hand.
 
Best regards.

What I observed is that A3 or A4 was brighter than the other notes, which I
first suspected as an need for voicing the hammer, but then i observed
that the A's above were brighter too... So, as I felt hard to believe the Idea 
of an illness specific to A strings, I wondered if the problem really from the 
hammers, or could instead come from a specific resonance of the piano 
itself on that frequency and the harmonics...
 
Your opinions ? possible ? not possible ? should I suspect the previous 
work ?
 
Philippe
