Psycho is Alfred Hitchcock's 1960 thriller, and its most famous musical moment comes from the shower scene, scored by Bernard Herrmann using only strings. Herrmann wrote the stabbing violin figures to mirror the violence on screen, and the sequence became one of the most imitated scenes in film history. Over the decades the sting has been quoted, parodied and sampled in trailers, television, comedy sketches and online videos, turning it into a universal signal for danger. Its short length makes it easy to reuse as a punchline or warning.
