The original chime was composed by Brian Eno for Microsoft's Windows 95, released in 1995, and quickly became one of the most recognisable computer sounds in the world. Years later, internet creators began re-pitching familiar songs and sounds into G Major, a key that makes them sound lower, slower and more unsettling. This Windows 95 edit follows that meme format, keeping the melody intact while giving it a distorted, ominous edge. It survives because the contrast between nostalgia and dread works instantly, even for viewers who never used Windows 95.
