Who Wants to Be a Millionaire began as a British television quiz show in 1998 and later inspired adaptations around the world. Its distinctive music was composed by father-and-son team Keith and Matthew Strachan, whose tension-building cues became central to the program's high-stakes atmosphere. The opening sound remains familiar because international versions retained the franchise's dramatic visual and musical language. Online, it continues to accompany trivia clips, parody competitions, escalating choices, and moments framed as potentially life-changing decisions.
