The shortest song in the world is less than 1 second long
The German band Royal Philharmonic Orchestra holds the Guinness World Record for the shortest song in the world, with their 1958 composition "The World's Smallest Recording." Measuring only 0.06 seconds long, the song consists of a single note on a harmonica. The record was set in 1958 and has yet to be beaten, making it a quirky and intriguing footnote in music history.
