FamousVertigo1958 · Bernard Herrmann
Prelude (main title): arpeggiated in triplets moving in contrary motion from the first bar, and held as a loud brass chord at the 'James Stewart' credit (bars 12–17)
An E♭ minor chord with a D added on top, written E♭m(maj7). The D sits a half step under the E♭ an octave up, so the chord rubs against itself and never feels settled. In Vertigo's opening titles Herrmann spins it as rising and falling arpeggios that turn like the film's spirals, and the brass hammer it out under the first credit.
Also called Hitchcock, minor-major seventh chord, Hitchcock Chord
