The melody comes from Jeopardy!, the American quiz show created by Merv Griffin, where the tune known as Think! plays during the Final Jeopardy thinking period. Griffin composed it for the show's original run in the 1960s, and it has since become shorthand for waiting for an answer. Flute covers like this one circulate widely online because the instrument keeps the tune instantly recognisable while sounding lighter and more homemade. That familiarity is why editors still reach for it for trivia, reaction videos and timed challenges.
