Most often when I think of some of the most distinctive musical moments in movie history, I'm drawn to the work of Ennio Morricone, or John Williams. Bernard Hermann comes to mind as well. Even James Horner has struck a chord or two that are iconic & unforgettable But if I'm going to select one piece of movie that is more distinctive than anything ever recorded for a movie, I have always thought that honor should go to the main theme from One Flew Over The Cuckoo's Nest. Not only does it perfectly capture the tone & absolute oddball heterodoxy of the film. I have to imagine that it may well be the only piece of music ever recorded, that combines a musical saw & a glass armonica in a duet for it's primary theme. It gives me goosebumps to this day, hearing it.
