Thanks for once again dispelling some of my erroneous ideas about pianos.

But the point is still taken that the sound board being a stiff board is
highly conductive of vibrations and is probably designed to not have a
lot of strong vibrational modes that are spatially or frequency
dependent.

It's nigh on impossible NOT to have many vibrational modes
that are both spacially AND frequency dependent. Look at some
laser interferometry or even the old talc-based resonance
patterns: the vibration patterns are horrifically complex and
all over the place from note to note.

Are they sufficient to create useful sound quality differences using several
mics?
