The shortest song in the world is under 1 second long
The song, called "Ring", was recorded by British musician Max Boyce in 1976. It's a mere 0.36 seconds long and features a solitary piano chord. The Guinness World Records recognized it as the shortest song in the world. The record was set to promote a Welsh-language newspaper, and Boyce has said he came up with the idea on a whim. The song has since become a novelty item, with some versions even featuring the chord being played twice to make it a full 0.72 seconds long.
