Guitar Hero is a rhythm video game series in which players match coloured notes on a guitar-shaped controller to rock songs, and a missed run quickly turns into a recognisable mess of wrong notes. Clips of those failures became a staple of gaming videos, fail compilations and livestreams, where the sound alone signals that a performance has collapsed. It remains popular because it is instantly understood even without the game on screen, giving editors a fast, funny shorthand for any blunder.
