Heavy metal as a style grew out of hard rock in the late 1960s and early 1970s, built around distorted guitars, strong bass and forceful drumming. Short riffs in that style later became a staple of online editing because they communicate intensity in seconds without needing lyrics. On soundboards and in short videos this kind of clip is shared as a ready made sting for entrances, parodies and exaggerated reactions. Its appeal has lasted because the sound is instantly recognisable, even when listeners do not follow metal music itself.
