You know that feeling. The fuse lights. The spark travels across the screen. Your heart rate immediately spikes because of five specific notes. Honestly, the Mission Impossible music score is probably the most recognizable piece of action cinema history, but most people don't realize it’s basically a giant musical joke played on the audience by a genius named Lalo Schifrin.
It started back in 1966. Schifrin, a legendary Argentine composer who had a deep background in jazz and classical music, was tasked with writing a theme for a new spy show. He didn't want something generic. He wanted something that felt like a pulse. Something nervous. Something that felt like a secret agent trying to outrun a ticking clock.
The Weird Math Behind the Mission Impossible Music Score
Most pop music or movie themes you hear are in 4/4 time. You can tap your foot to it easily. One, two, three, four. Easy. But Schifrin decided to be a bit of a rebel. He wrote the original theme in 5/4 time.

Why does that matter? Because 5/4 is inherently "unbalanced." It feels like it’s missing a beat, or like it has one too many. It creates a physical sense of urgency. You can't quite relax into it. Schifrin famously joked that he wrote it for "people with five legs." It’s basically the musical equivalent of a person running and occasionally stumbling but never falling.
If you look at the Morse code for the letters "M" and "I"—for Mission Impossible—it gets even cooler. In Morse code, "M" is two long dashes (--). "I" is two short dots (..). If you listen to that iconic bassline—dun dun, da da—it’s literally the initials of the show played out in rhythm. Two long notes, two short notes. It’s a literal "hidden in plain sight" easter egg that has survived for over half a century.
When Danny Elfman took over for the first Tom Cruise film in 1996, he had a massive challenge. How do you take a 60s TV theme and make it feel like a high-octane 90s blockbuster? Elfman leaned into the orchestral weight. He kept the 5/4 signature but made it feel massive, like it was being played by a literal army. It set the stage for every composer who followed, from Hans Zimmer to Michael Giacchino and Lorne Balfe.
From Jazz to Metal: The Evolution of the Theme
Every director has brought a different flavor to the franchise, and the music followed suit. When John Woo stepped in for Mission: Impossible 2, he brought Hans Zimmer with him. This was the year 2000. Nu-metal was everywhere. So, naturally, we got a version of the theme that featured Limp Bizkit.
"Take a Look Around" became a massive hit. It took that 5/4 riff and flattened it out into a 4/4 rock beat so people could actually headbang to it. Purists hated it. Kids loved it. It showed that the Mission Impossible music score was durable enough to survive almost any genre shift. It’s a "chameleon" piece of music. It can be a sleek jazz lounge track or a stadium rock anthem without losing its soul.

Michael Giacchino eventually took the reins for the third film and the fourth (Ghost Protocol). Giacchino is a student of the classics. He brought back the bongo drums. He brought back the brassy, 60s spy aesthetic but mixed it with modern percussion. He understood that the music isn't just background noise; it’s a character. In Ghost Protocol, he even infused the score with Russian musical influences to match the Kremlin-hopping plot.
Why Lorne Balfe Changed Everything in Fallout
By the time Mission: Impossible – Fallout rolled around, the stunts were getting insane. Tom Cruise was jumping out of planes at 25,000 feet. The music needed to be heavier. Enter Lorne Balfe.
Balfe did something radical. He didn't just play the theme; he deconstructed it. He used massive percussion sections—sometimes 12 drummers at once—to create a "wall of sound." He took the familiar motifs and slowed them down until they sounded like a threat rather than a jingle.
In the "The Exchange" track from Fallout, you can hear the influence of pure tension. It’s not about the melody anymore. It’s about the vibration in your chest. Balfe realized that after six movies, the audience knows the theme so well he doesn't have to hit them over the head with it. He can just hint at it, and our brains fill in the rest.
The Challenges of Writing Action Music Today
Modern film scoring is a bit of a battlefield. There’s a lot of "temp music" where directors edit a movie to an existing score and then tell the composer to "make it sound like that." It leads to a lot of boring, generic music.
But the Mission Impossible music score resists this because its DNA is so specific. You can’t "genericize" a 5/4 time signature easily. It demands a certain level of technical skill from the musicians. If the trumpet players aren't on their game, the whole thing falls apart. It’s high-wire music for high-wire movies.
Interestingly, Lalo Schifrin is still around to see his creation evolve. He’s seen it played by orchestras in Vienna and remixed by DJs in Ibiza. He’s often said he’s surprised it became such a phenomenon. To him, it was just a clever solution to a TV pilot's needs.
Actionable Steps for Music Fans and Creators
If you want to truly appreciate the complexity of these scores, or if you're a creator looking to use tension in your own work, stop listening to the music as a whole and start breaking it down into parts.
- Listen to the "Stair Bridge": In the original theme, there is a section where the brass rises in pitch. This is designed to create anxiety. Notice how modern versions use digital synths to stretch that feeling of "rising" indefinitely.
- Isolate the Percussion: Find the "Fallout" soundtrack on a good pair of headphones. Ignore the strings. Just listen to the drums. It’s a masterclass in how to use rhythm to simulate a racing heartbeat.
- Try the 5/4 Challenge: If you’re a musician, try to play a simple melody in 5/4. It’s harder than it looks. It forces your brain to stay "on" because you can't rely on the standard 4-beat loop.
- Compare the "Drums and Bass": Compare the M:I-2 version by Zimmer to the Dead Reckoning version by Balfe. You’ll see how cinematic trends shifted from "cool and detached" to "visceral and overwhelming."
The Mission Impossible music score isn't just a theme song. It’s a masterclass in psychological manipulation through sound. It uses weird math, hidden Morse code, and sheer volume to make sure that for two hours, you’re just as stressed out as Ethan Hunt is.
Next time you watch one of the films, pay attention to the moments when the theme isn't playing. Usually, the composer is using fragments of the melody—just two or three notes—to signal that a plan is coming together. It's the musical equivalent of a "wink" to the audience. That’s the mark of a score that doesn't just fill space, but actually tells the story.
To get the full experience, seek out the 2015 "La-La Land Records" expanded releases of the original television scores. They contain hours of Schifrin’s original sessions that show just how much jazz experimentation went into what we now consider a standard action movie soundtrack. You’ll hear flutes, weird percussion, and experimental piano riffs that never made it to the radio but defined the "spy sound" for decades.
