Scoring ‘Smile,’ Sans Strings or Synths: How the Composer Made a Horror Hit Even Creepier With an Unusual Instrument

Mike Wass With global box office receipts already exceeding $100 million, “Smile” is the breakout horror hit of 2022. And while pundits largely put the film’s success down to Parker Finn’s spooky premise and a razor-sharp marketing campaign, its secret sauce is arguably Cristobal Tapia de Veer’s inventive score.

Built around an obscure instrument that mimics human growls and groans, the otherworldly soundscape adds a layer of dread to “Smile” that lingers long after the credits roll. “Besides being the creepiest score of the year, Parker wanted it to be original,” Tapia de Veer says of the director’s original brief.

To achieve that formidable goal, the Chilean-born composer knew that he had to sidestep the genre’s obsession with synthesizers. “In the last few years, there has been an obsession with retro sounds from the ’80s,” he says. “It’s very hard to plug in a synthesizer and not sound like John Carpenter when you start doing creepy things.” Creepy strings were also off the table given their hallowed status in horror.

Instead, Tapia de Veer turned to the daxophone, which is essentially a thin plank of wood that is played with a violin or double bass bow. “I was interested in it because you can play notes that sound like human voices,” he says, before adding drily: “it’s pretty weird sounding.” The daxophone became the lead instrument for the score, although synthesizers were still used sparingly.
