I think I posted once that organs have been known to do damage to cathedrals, churches and buildings because they are the only instrument that can produce physical sound. Notes below CCC have such low frequencies that they make a shockwave that will rattle a building down to the bedrock. That kind of sound doesn't record or reproduce well but here's a video of the organ at Aarhus Cathedral in Denmark. At 0:34 and 0:35 you can hear CCCC being played on the pedal division. There's a longer hold of it at 4:20. It's sound frequency is eight hz or eight cycles per second. That can crack plaster, loosen boards, and even cause mortar to be shaken loose between stones. You can actually watch that happen at the Cadet Chapel at West Point. Recordings don't do it justice because when you witness it in person you can literally feel the entire cathedral or building shaking.Here is a fine video with great organ music of the Baroque St. Stephen's Cathedral in Passau, Germany - One of the Largest Organs in the World.
