All In Your Head

People who make horror movies know: if you want to scare someone, use scary music. There are two fundamental ways to make music scary. The first way is to compose music with lots of screechy, irregular tones, imitating the sounds of screams and distress. It’s a biological trigger for “Something terrible is happening right now!”

The second way horror movie music makes you feel uneasy is to go the other direction: low grumbling sounds. This is also rooted in biology, since the lowest frequency a species can produce is a function of its body size. Low-frequency sounds mean that something big is around.

Mix these two and you’re on your way to creating a classic scary soundtrack.

Most of the time, this horror movie music exists outside the world of the story. It’s not heard by the characters, just the audience. it’s an effect heard

But this is not the case in the TV series Hannibal.

Hannibal tells the story of a serial killer named Hannibal Lecter, whom you may know from Silence of the Lambs and Manhunter. The show is kind of a prequel to those stories.

Composer Brian Reitzell’s score for Hannibal lives half in music, half in sound design. You get a sense that it is heard by the characters, inside their imaginations, as it transports you directly into the action.

For example, in a scene where Hannibal rides a motorcycle, instead of using the recorded sound of an actual motorcycle, Brian creates a new sound in the studio that makes the viewer feel like they are actually riding.

Brian slid his fingers up and down the neck of a bass to produce a kind of revving sound. He mixed it with castanets to represent the ignition, bowed wooden block to represent the flames from the engine, and added some reverb to create a smoky texture. It’s a sound that evokes the feeling of wind whipping past, the rush of adrenaline, and the engine rumbling below.

The other main character in the series is Will Graham, an FBI profiler who has a knack for getting inside the heads of serial killers to try to catch them. At times, the sound design of Hannibal places the viewer inside Will Graham’s head.

Executive producer David Slade—who also does the sound mix of every episode—wanted the audience to hear the sounds of Will Graham’s brain at work. He created the clicking, crackling sounds of synapses firing by sampling and exaggerating the sounds from a Newton’s Cradle.

The bad guy in Hannibal is Hannibal Lecter, of course, but Will Graham is also wrestling with his own demons. He has the dreamlike visions of a demon they call the Wendigo, which represents both the evil of Hannibal and the evil growing inside of Will Graham.

To represent the Wendigo, Brian and David wanted a sound that indicated the coming of that character. They knew they wanted something ominous and circular-sounding. They found it in a bullroarer—essentially a piece of wood on a string. It’s one of the oldest instruments.

Slade pitched the sound of the bullroarer up and down to make it scarier. Once they paired it with the image of the Wendigo, they knew it was a sonic fit. It matched the emotions of the visual and augmented the presence of the Wendigo in the story.

The fact that an internal soundtrack feels appropriate and natural, even in the real world where no “soundtrack” should exist, maybe a reason why music soundtracks are a ubiquitous part of the design of movies and television. And why it’s really not a good idea to watch Hannibal right before going to bed.

    Great interview, the sound on this show is amazing! One of the many things people don’t think about when watching TV is the sound/soundtrack.

    The Hannibal soundtrack is an additional character in the show, it supports the acting and drives the mood. The ticking clock that ran through Mizumono built the tension, even if you weren’t always consciously aware that you were hearing it. Ever since I noticed the strength of the soundtrack, I often listen to Hannibal through headphones to fully immerse myself in the detail. Congrats and thanks to Brian and David for their amazing work!

    I’ve loved 99pi for a while now, but they may have lost a listener now that they got me hooked on Song Exploder.

    That segment from Song Exploder is likely the best thing I’ve ever heard in six years of listening to podcasts every day. I can never say what nerve it touched, but it was palpable.

    Driving in early,not many cars on the road, listening to this episode on my way to work. A car passed me unexpectedly on my right, and it scared the s**t outa me! All because of that creepy music you made me listen to! It worked. :) Great episode!

    When John Roderick is talking about the crew compartment breaking up, I got gooesbumps and nearly cried. At work. Thank you for that. It sounds snarky, but I’m serious. Thank you!
