The sound comes from Scatman, the 1994 breakthrough hit by American musician Scatman John, whose real name was John Paul Larkin. A jazz pianist and singer who stammered, Larkin turned his stutter into rapid scat singing, and the song became a major dance hit in Europe before reaching listeners worldwide. Decades later, the catchy, high-speed vocal hook found a second life online, where short clips are reused in memes, edits and dance videos for its instant, feel-good energy.
