John Debney was the composer for Elf.

It wasn't "most" of Hitchcock's films -- only seven -- but Hitchcock and Bernard Herrmann did great work together. The composer wrote the theme for Psycho , for instance.
The Alfred Hichcock movie "Psycho" had three direct sequels: Psycho II, Psycho III, and Psycho IV: The Beginning(technically Psycho IV was a prequel)There was also a (rather inferior) 1998 remake of the original Psycho.There is also a Hindi language movie called "Psycho" which is a completely unrelated story.
The sound effect used in the famous Psycho shower scene was created by composer Bernard Herrmann using violins played with extreme intensity and a rapidly repeated stabbing motion to mimic the sounds of a knife attack. The effect can be found in the original soundtrack of the movie or various compilations of film scores.
