The music comes from Mozart's 1791 opera The Magic Flute, where the Queen of the Night sings her famously demanding aria, Der Hölle Rache, in a moment of furious determination. Centuries later the passage found a second life on TikTok, where the opera challenge asks creators to attempt its extreme high notes, often in one take. Its spread was driven by reaction videos, duets and failed attempts that are as entertaining as successful ones. It remains popular because the aria is instantly recognisable, technically daunting and perfectly suited to short, dramatic performance clips.
