The music score for The 7th Voyage of Sinbad was composed by Bernard Herrmann, better known at the time for his collaboration with the director Alfred Hitchcock. Herrmann went on to write the scores for three other Harryhausen films: Mysterious Island, The 3 Worlds of Gulliver, and Jason and the Argonauts. Of the four, Harryhausen regarded the score for The 7th Voyage of Sinbad as being the finest, due to the empathy Herrmann's main title composition evoked for the subject matter.
