Composed by Nino Rota for Francis Ford Coppola's 1972 film The Godfather, adapted from Mario Puzo's novel, the theme became one of cinema's most recognisable pieces of music. Its association with Don Vito Corleone and the Corleone family turned it into cultural shorthand for the mafia, loyalty and organised crime. Decades later it spread far beyond the film through parodies, television, sports entrances and online memes, where just a few notes instantly signal a powerful figure arriving or a deal being made.
