I was tuning a C7 in a theatre pit (aboard a ship) today. I was told it was OK to tune as long as I didn't mind riding up and down on the pit elevator. They were testing it. "Sure, why not!" What an eye-opener for sound and temperature! As I started tuning in the pit, the sound was bouncing all over, real easy to hear, hitting me in the face, bouncing around, but as the piano (and I) rose up into the cavernous theatre, the sound magically disintegrated and strained to fill the room. Shortly I felt the wrap-around feeling of the cool air conditioning surrounding me and the piano and subsequently saw the red-lights on the SAT starting to run clockwise. Then the elevator started downward and this phenomina was repeated again in reverse. A couple of times doing this was a real eye-opening experience in accoustics and piano stability. FWIW.
