Schifrin's music cues ("Scorpio's View" and "Main Theme") imbued one of the most iconographic opening sequences in the thriller genre with an astonishing musical counterpoint (as we watch "The Scorpio Killer" murder his first victim with a Sniper Rifle and Harry Callahan pieces together the killing).
A splendid cocktail of jazz, rock, orchestral suite, psychedelic abstraction and vocals, it remains a still unsurpassed musical touchstone in cinema.
