What Is the Time Signature of the Ominous Electronic Score of The Terminator?

A Slate investigation.

(Continued from Page 1)

When I Googled the score’s composer, Brad Fiedel, I found a tantalizing tidbit. “Terminator was very difficult,” said Fiedel, “because I was using many different synths and sequencers and because I didn’t have midi available on many of them I had to sync them by hand. This is why the main theme is in a very odd time signature. The looping of the Prophet-10 was just a little short of a complete measure.”

At this point I needed to know the full story. So I found Fiedel and got him on the phone. He was happy to take me back to the early ’80s and set the scene. He explained that before The Terminator, he’d worked on a score for a TV movie about Hitler’s last days. The producers were concerned that lush string music might lend sympathy to Hitler, so Fiedel conjured up a crashing, metallic ruckus. It was this sound that formed the germ of the later Terminator score.

Fiedel was at heart an improviser. To create the Terminator theme, he first set up a rhythm loop on one of the primitive, early-’80s devices he was using. (In those days, Fiedel was firing up a Prophet-10 and an Oberheim.) He recorded samples of himself whacking a frying pan to create the clanking sounds. Then he played melodic riffs on a synthesizer over the looped beat. Amid the throes of creation, what he hadn’t quite noticed—or hadn’t bothered to notice—was that his finger had been a split-second off when it pressed the button to establish that rhythm loop. Being an old machine, there was no autocorrection. Which meant the loop was in a profoundly herky-jerky time signature. Fiedel just went with it. The beat seemed to be falling forward, and he liked its propulsiveness. He recorded the score that way and (not being classically trained) never wrote down any notation. The music he’d improvised went straight into the film. With its collaboration between fallible humanity and rigid machinedom, the score was especially well-suited to the material at hand.


Much like the creators of Skynet, Fiedel was only later forced to consider what he had wrought. He got a call from the legendary film and TV composer Henry Mancini, who was planning to record an album of movie scores with a full orchestra. Fiedel was giddy to learn that Mancini wanted to include the Terminator theme. But then Mancini asked for the “lead sheet”—the notes the bandleader would use so the orchestra musicians could walk in off the street and nail the recording in one take.

Fiedel enlisted a friend named George Kahn, a jazz musician who had a music degree and more formal training, to help set the score to paper. “He called me up and said, ‘Brad, what time signature is this in?’ I said, ‘I dunno, 6/8?’ He said, ‘No, it’s quirkier than that.’ ” (Incidentally, a subsequent search turned up the fact that Fiedel related a version of this anecdote to Film Score Monthly in 2013. I don’t know why it didn’t show up on my computer in my initial search. I’m blaming our capricious machine overlords.)

“Brad works mind to fingers to keyboard,” Kahn says now, “and he bypasses paper. So I had to sit down and figure it out.” You might say it was as though Kahn had been sent back in time to the early ’80s—dropped into a world that wasn’t his own and he didn’t understand—on a mission to safeguard the conception of a precious thing that he hoped would live on into the future.

And the verdict? “It’s in 13/16. Three plus three plus three plus two plus two.”

Sure enough, primed to listen for this grouping, I was at last able to count out the beat. DAH-two-three-DOONK-two-three-CLANK-two-three-GONK-two-GONK-two. Never has drumming on my thigh felt so cathartic.


Brad Fiedel went on to write the theme for Terminator 2: Judgment Day (in the much less jarring time signature of 6/8, because he felt that film had more warmth), and scored various other film projects before leaving Hollywood to make his own music. He’s currently producing a one-man musical about the artistic arc of his career.

George Kahn is a touring jazz musician with his own record label.

Henry Mancini sadly died before he could record that album of movie scores.

The Skynet artificial intelligence system went online in 1997, quickly achieved self-awareness, and remains dedicated to the extermination of all humanity.
