The world's smallest song is just 2.5 seconds long
In 2000, British musician David Fisher created a 2.5-second long song called "The Girl and the Robot" using a software that allowed him to compress music to an extreme degree. The song was played on a CD single and verified by the Guinness World Records as the shortest song ever recorded. Fisher's tiny tune was a novelty, but it sparked debate among music enthusiasts about the minimum length required for a song to be considered music.
