reverberation off of hard surfaces, not unlike false beats

There must be an organ in there.  Organists love 30-seconds of reverb
time!

This is one of the most miserable things that can happen to a good
piano.  
I tuned one yesterday that is in a chapel/recital hall.  The arched
plaster ceiling above the stage has just been restored.  Clap once and
the hall gives you a round of applause. 
The beat rate will be the same from note to note, so eventually you
learn to ignore it. 
I'm glad I got to hear the piano before it was moved to that stage.

>Yesterday evening, I was tuning in a cavernous mansion with marble
tiled floors, cathedral ceilings, and no carpets, pictures or tapestries
to baffle the sound.  Going through the upper two octaves, it was
extremely hard to differentiate between beating and echoing.  Then there
was the "thwack" of the hammers that bounced all over creation, not to
mention the notes that really did have "false" beats.
