Did you know that #PipeOrgans were first invented in the 3rd century BC in ancient Greece? Uh-huh. And for a millennia pipe organs were the largest “machines” on the planet? So of course #Bach composed for the impressive instruments - which got bigger and even more impressive as cathedrals started to be constructed. It took a lot of pipes to fill a massive, stone cathedral with sound! #music #OrganMusic #MusicVideo #ClassicalMusic

A friend who is an organist and organ tech took my family on a tour of pipe organ innards. This is one of the largest pipe organs in the state of North Carolina.

Nerding out at a pipe organ concert being given by my old organist from Edinburgh, Dr John Kitchen. We're in the public theater, opposite the chapel, in Trinity College Dublin. #PipeworksFestival #PipeOrgans #TheatreOrgan #TCD #OrganMusic
@austinphilp Very cool! Looks as pretty as I’m sure it sounds. We have two pipe organs in our house #pipeorgans #classicalmusic
@mediaarchaeologylab totally #surreal #bizarre makes me itchy also reminds one of #PipeOrgans and the practice #Cockpits some pilots make

An explanation for why the fundamental tone of pipe instruments is lower than expected.

"When an organ pipe sounds, a vortex [...] forms over the pipe’s rim, the team reported March 14 in Chicago at a meeting of the American Physical Society. What’s more, this vortex is capped by a hemisphere of resonating air."

Here’s why pipe organs seem to violate a rule of sound

Why reedless wind instruments’ fundamental tones are lower than expected is an 160-year-old mystery. Physicists have now solved it.
