This is the world's largest tuba. Or, according to Carl Fischer Music, what "some believe is the world's largest tuba." It dates back to 1900, and is, as one might expect, quite large. So large, that it takes two human beings -- and an estimated four lungs -- to play it.
"It's not playable like a regular tuba," Steve Dillon, owner of Dillon Music, explains in the video above. He's the one propping the tuba up while Derek Fenstermacher, principal tuba at the New Jersey Symphony Orchestra, attempts to squeeze notes out of the behemoth brass marvel. "But if it looks like a duck and quacks like a duck, it's a duck. You can play fundamental tones on it."
Wait, is it a duck? Either way, take a second to watch Fenstermacher play the duck/instrument in this great clip, created by The New York Times.
