How John Carpenter Made the Halloween Theme, and the Synths That Scared the 80s

One of the most famous pieces of horror music was written because a studio executive wasn't scared. In 1978 John Carpenter showed a rough cut of Halloween to a young Fox executive, and it didn't scare them. Carpenter's plan was to "save it with the music." He did it himself, because, in his words, "I was the fastest and cheapest I could get."

The result is a piano figure in an odd time signature, a few synth notes and a pulse. It still works 48 years later, and the habit behind it, one person and a keyboard instead of an orchestra, shaped 80s horror and, much later, synthwave.

A $300,000 movie and a $10,000 director

Halloween cost about $300,000. Carpenter was paid $10,000 to write, direct and score it, plus 10 percent of the profits. It was shot in 20 days in May 1978, premiered in Kansas City on October 24 and opened on October 27. It made about $70 million worldwide.

There was no money for an orchestra. Carpenter later said he simply couldn't afford one, and only came to love synthesizers afterward. He also can't read music. He's said he can play almost any keyboard but can't read or write a note. In the credits he billed himself as the "Bowling Green Philharmonic Orchestra."

How the theme was recorded

The score was recorded at Sound Arts Studio in central Los Angeles. Sources disagree on how long it took: some say about three days, others about two weeks. Carpenter has said the main theme itself took about an hour.

The strange part is that he recorded it without watching the film. The music was composed and played in the studio to a click track, with cues timed by stopwatch, and cut to the picture later. Nobody was scoring scene by scene. He was building blocks of dread and trusting they'd fit.

The gear belonged to Dan Wyman, a synth programmer and San Jose State music professor who had worked on Carpenter's Assault on Precinct 13. Wyman tuned the synthesizers and ran the recording. Carpenter put it simply: "He would tune up the synths and do the recording for me." Wyman called Carpenter's riffing "really intelligent noodling."

Which synths, exactly? Nobody knows for sure. Carpenter has said the pulse came from an electronic box "almost like a drum machine," and he can't remember the model. You'll see Prophet-5 named online. Treat that as a guess for 1978. His own line sums up the method: "We used what was at hand."

Why it sounds so wrong

The piano line is in 5/4, five beats to a bar instead of the four almost every pop song uses. Carpenter learned the rhythm as a bongo exercise from his father, Howard Ralph Carpenter, a music professor, back in 1961.

Berklee's analysis breaks down the rest. The beats are grouped 3+3+2+2, so the pattern lurches forward like it's missing a step. The right hand hammers C sharp up to F sharp, a tritone, one of the most unstable intervals there is. Then it drops a half step, which feels like falling out of key. Under that sit long low synth notes and a steady electronic pulse in 16th notes.

If you want to feel it, clap ten even beats and hit the first, fourth, seventh and ninth hard. That's the engine of the whole film. The other cues are even simpler: the "Michael Kills Judith" sting is three notes of a thin synth tone, and the stalking music leans on notes a half step apart.

The Carpenter and Howarth years

For Escape from New York (1981), editor Todd Ramsay introduced Carpenter to Alan Howarth, a Cleveland-born synth tech who had worked with Weather Report and on sound effects for Star Trek: The Motion Picture. Carpenter visited Howarth's home studio for about three hours and they agreed to work together. Carpenter wrote and played. Howarth ran the machines. Carpenter's job description for him: "Alan, that's your job. Don't even waste my time."

Together they scored Halloween II (1981), Halloween III (1982), Christine (1983), Big Trouble in Little China (1986), Prince of Darkness (1987) and They Live (1988). Escape, Halloween II and Christine used the Sequential Circuits Prophet-5, and Halloween II added a Prophet-10, an E-mu Emulator and a Linn LM-1 drum machine. Without MIDI, every layer was played by hand onto tape. Howarth's summary of the era: "There was no cut and paste."

By They Live they were syncing picture to a 24-track machine and using a Synclavier, which Howarth called "the NASA of samplers."

The one big exception is The Thing (1982). Carpenter flew to Rome to hire Ennio Morricone, played him the Escape score as a reference, and Morricone wrote about an hour of music. Most of it went unused, and Carpenter and Howarth added a few simple electronic cues. Some unused Morricone pieces later turned up in Tarantino's The Hateful Eight.

Everyone else's cheap, scary synths

Carpenter wasn't alone. Low budgets and new machines made the 80s horror sound.

Goblin. The Italian band behind the Suspiria score, a film Carpenter named as an influence. Dario Argento gave them one night to write and one day to record Profondo Rosso (1975), and the soundtrack spent 52 weeks on the Italian charts. They also scored Suspiria.

Friday the 13th (1980). Harry Manfredini wrote the score in about two weeks and recorded it in a friend's basement. The famous whisper is "ki ki ki, ma ma ma," short for "kill" and "mommy," run through an echo unit. As Manfredini put it: "Everybody thinks it's cha, cha, cha."

The Terminator (1984). Brad Fiedel played the theme on a Prophet-10. Its odd 13/16 rhythm came from a sequencer loop that was set up wrong by accident and sounded better that way.

A Nightmare on Elm Street (1984). Charles Bernstein's synth score sat under a film that cost about $1.1 million and made about $57 million worldwide.

Tangerine Dream. The German band scored more than 20 films in the 80s, including Thief, Firestarter and Near Dark.

From the 80s to synthwave

Vinyl reissues of his old scores brought Carpenter a new audience, and in 2015 he released Lost Themes, an album of new instrumental music made at home with his son Cody Carpenter and his godson Daniel Davies. It reached No. 44 in the UK. He played his first ever live shows after that. More Lost Themes albums followed, the fourth in 2024.

The same trio scored Halloween (2018), this time recorded to picture, all synths, no orchestra. That film made about $260 million on a $10 million budget. They also scored Halloween Kills and Halloween Ends.

Synthwave lists Carpenter, Vangelis, Jarre and Tangerine Dream as its roots, and the darker branch, darksynth, leans hardest on Carpenter and Goblin. If that's your lane, we've covered what horror synth and darkwave are and who Carpenter Brut is.

Make your own 1978 cue

The method is still free. Use whatever synth or plugin you have. Set a click, play a simple piano figure in five, put long low notes under it and a steady 16th note pulse on top. Don't watch the scene while you play. Then drop it under the footage and see what lines up.

And if you'd rather wear the genre than play it, the 808 T Shirt ($39.99) nods to the drum machine era, and the Into The Night Hoodie 1981 ($69.99) and Retro Vinyl Hoodie 1982 ($69.99) suit a cold October night with Lost Themes playing.

Questions we get

What time signature is the Halloween theme in? 5/4, five beats to the bar, often counted as 3+3+2+2 eighth notes.

How long did it take to write? Carpenter has said the theme took about an hour. Recording the whole score took somewhere between a few days and two weeks, depending on the source.

What synthesizer was used on Halloween (1978)? Nobody knows for sure. Carpenter doesn't remember, and the gear belonged to programmer Dan Wyman. The Prophet-5 is documented on his early 80s scores.

Did John Carpenter score The Thing? Ennio Morricone did. Carpenter and Alan Howarth added a few electronic cues.

Who made the music for Halloween (2018)? John Carpenter, his son Cody Carpenter and Daniel Davies.
