Herrmann biographer Steven C. Smith writes that the music for the shower scene is "probably the most famous (and most imitated) cue in film music," but Hitchcock was originally opposed to having music in this scene. When Herrmann played the shower scene cue for Hitchcock, the director approved its use in the film. Herrmann reminded Hitchcock of his instructions not to score this scene, to which Hitchcock replied, "Improper suggestion, my boy, improper suggestion." This was one of two important disagreements Hitchcock had with Herrmann, in which Herrmann ignored Hitchcock's instructions. The second one, over the score for "Torn Curtain" (1966), resulted in the end of their professional collaboration. A survey conducted by PRS for Music, in 2009, showed that the British public consider the score from 'the shower scene' to be the scariest theme from any film.
