Mark Korven's original soundtrack for 'The Lighthouse,' starring Robert Pattinson and Willem Dafoe, marks his second collaboration with director Robert Eggers (The Witch)."Robert [Eggers] and I were rather like the two wickies that went insane in The Lighthouse, musically speaking.

We travelled to some very dark harmonic and textural places. We both enjoy not just breaking the rules, but blowing them to smithereens.

The spirit of experimentation was always present."-Composer Mark Korven"Composer Mark Korven and I developed a shorthand working together on The Witch.

This made collaborating on The Lighthouse an incredibly enjoyable process. But it was not without its many challenges.

Originally, I wanted a score with no strings at all. The Witch soundtrack was so string-prominent that I wanted a full departure.

I only wanted horns, pipes, conch shells, concertina - things that sounded like the sea - or the lighthouse station's ominous foghorn.

It would be a minimalist aleatoric soundtrack with a nod to sea shanties and ancient Greek music.

As Mark and I embraced the sound of big brass sections, it quickly became a maximalist aleatoric soundtrack.From the beginning, Mark thought that we might need some string textures to tell the story and that I was being foolhardy.

As usual, he was right, but it took some time for me to hear that I was wrong. We eventually set up an experimental session with a cellist and a double bass player to create some strange, otherworld- ly sounds to use in moments of high tension, rather than relying on the tried and true Penderecki-esque string rises of horror cinema (although we still use a couple).

These strings would be obscured and camouflaged. I was fine with that.To create the ethereal and monstrous sounds of the light itself, Mark experimented with the waterphone, glass harmonica, his famous Apprehension Engine - as well as friction mallets drawn across cymbals, wood, and glass.

This beautiful work of Mark's, combined with Damian Volpe's sound design, does so much to convey the inner world of Rob and Willem's characters."-Director Robert Eggers
