The secret Morse code hidden inside the iconic Mission: Impossible theme song
In short: Lalo Schifrin, the legendary Argentine-American composer, turned a simple rhythmic pattern into one of television's most recognizable motifs. By utilizing an unusual 5/4 time signature, he encoded the letters M and I into the very heartbeat of the Mission: Impossible theme, forever changing the sound of suspense in cinema.
Born in Buenos Aires in 1932, Boris Claudio Schifrin was steeped in music from childhood, as his father led the Buenos Aires Philharmonic for three decades. After studying at the Conservatoire de Paris under masters like Olivier Messiaen, Schifrin moved to New York in 1960 to join Dizzy Gillespie’s quintet. This transition from jazz pianist to Hollywood titan defined his career, as he seamlessly blended complex jazz harmonies, Latin rhythms, and traditional orchestration to create a signature sound that dominated film and television for decades.
Schifrin’s filmography is a masterclass in versatility, ranging from the gritty, funk-infused score of Enter the Dragon to the iconic, jazz-inflected themes of Bullitt and Mannix. His work was not always met with immediate success; his original, intense score for The Exorcist was famously rejected by director William Friedkin, leading to what Schifrin described as one of the most unpleasant experiences of his life. Despite such setbacks, his influence remained pervasive, with his compositions sampled by hip-hop artists and his arrangements anchoring the global success of The Three Tenors.
Beyond his film work, Schifrin was a relentless innovator who viewed music as an infinite field of exploration. Whether composing a 35-minute symphony in 2025 or founding his own record label, Aleph Records, in 1998, he consistently pushed boundaries. His legacy, recognized by five Grammy Awards and an Honorary Academy Award, is that of a composer who bridged the gap between the concert hall and the silver screen, proving that the possibilities of sound combinations remain vast and largely untapped.
