How many decades have directors of horror films been using scratchy, high-pitched howls to make sure that audiences understand that something horribly scary is happening? I guess it began with Bernard Herrmann‘s screechy violins on the Psycho soundtrack. I only know that you can’t watch a horror film or a trailer for one without hearing that shrieking laryngitis banshee wail — the universal sound for all ghosts, demons, banshees and monsters. I’d really love to be spared every so often.
