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.
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."
