Morse Code in Songs: Hidden Messages in Music

Rush – "YYZ": an airport code as a riff

The most famous example among musicians is "YYZ" by the Canadian rock trio Rush, from their landmark 1981 album Moving Pictures. The song opens with a distinctive, stuttering rhythm in an unusual 5/4 time signature — and that rhythm is literally the letters Y-Y-Z tapped out in Morse code.

YYZ is the airport identifier code for Toronto Pearson International Airport, the band's home airport. Drummer Neil Peart and bassist Geddy Lee reportedly got the idea after hearing the YYZ identifier beacon transmitted in Morse as their plane approached Toronto to land. In Morse, Y is –·––, Y again is –·––, and Z is ––··, and you can hear that exact pattern hammered out in the instrumental's intro. It's a near-perfect piece of musical Easter-egg craftsmanship: the title, the opening melody, and the hidden code are all one and the same thing. Decades of fans have decoded it, and it's become the go-to example whenever anyone asks whether real bands have actually hidden Morse in their music.

"Better Days" – a pop song that rescued hostages

This is the story that stops people in their tracks, because it isn't a cute Easter egg — it genuinely helped save lives. In 2010, the Colombian army faced a heartbreaking problem: hundreds of soldiers and police officers were being held hostage by FARC guerrillas deep in the jungle, some of them for more than a decade. Crucially, many of the captives were former communications specialists who knew Morse code by heart.

So the military worked with advertising creatives to produce an actual radio-friendly pop song, "Better Days" (in Spanish, "Mejores Días"), credited to the duo Natalia Gutiérrez y Angelo. Hidden inside the chorus — disguised within a synthesizer melody and deliberately masked by the guitar and drums — was a Morse code message that translated to roughly "19 people rescued. You're next. Don't lose hope." The whole plan rested on a clever asymmetry: the captured soldiers could recognize Morse, but their untrained FARC guards almost certainly could not.

The song was pushed out to more than 130 small radio stations and heard by an estimated three million people. Rescued hostages later confirmed in their debriefings that they had heard and understood the hidden code, and that the message spread quietly from prisoner to prisoner. It's one of the most extraordinary real-world uses of Morse code in the 21st century — a genuine covert operation delivered through a catchy dance-pop track. The Exploratorium and numerous news outlets have documented the campaign in careful detail, and it remains the single most compelling answer to anyone who thinks Morse code is a dead relic.

Duran Duran – "The Union of the Snake"

Synth-pop giants Duran Duran got in on the game too. On their 1983 hit "The Union of the Snake," keyboardist Nick Rhodes slipped a Morse-code-style figure into the arrangement — a high-pitched keyboard line playing three short notes, three long notes, and three short notes again, which is of course the classic SOS rhythm. It's audible around the 21-second mark and surfaces again later in the track.

It's worth being honest about this one rather than overselling it: it's more of a stylistic wink than a genuine secret dispatch, and the notes don't all map cleanly onto meaningful text beyond that recognizable SOS shape. But the SOS pattern itself is deliberate and clearly recognizable once you're listening for it, and the example shows something important about how Morse works in pop culture. The aesthetic of Morse — that hypnotic, insistent short-long-short beeping — became a texture that producers reached for whenever they wanted to inject a sense of signal, mystery, distress, or old-fashioned radio into a record.

Kraftwerk, Roger Waters, and Morse as texture

Beyond hidden titles and covert operations, plenty of artists have used Morse purely for atmosphere and meaning. German electronic pioneers Kraftwerk built the very sound of telegraphy into their work — their track "Radioactivity" features Morse code that actually spells out the word "radioactivity" itself, turning the code into a literal part of the composition's subject matter rather than a buried joke.

Roger Waters, of Pink Floyd fame, has woven Morse-style signaling across his solo material, layering the beeps into records preoccupied with communication, war, broadcast, and surveillance. The pattern repeats across genres and decades: whenever a producer wants to evoke transmission, espionage, distress, or the crackle of a distant radio station, a short burst of dots and dashes does the job instantly and needs no explanation. Morse has effectively become a kind of universal sonic shorthand for "there is a hidden signal here" — which, rather beautifully, is exactly what it literally is.

• Rush: a title encoded directly as a riff.
• The Colombian army: a real, life-saving rescue message.
• Duran Duran: an SOS-flavored stylistic nod.
• Kraftwerk: the code as the literal subject matter of the song.
• Roger Waters: Morse as thematic atmosphere and mood.

How to spot Morse in a track yourself

Once your ear is primed, finding these hidden signals becomes a genuinely fun listening game. A few things to listen out for:

• A repeating, non-musical rhythm of clearly short and long pulses, often sitting on a single unchanging pitch — a beep, a bleep, or a percussive tap that doesn't quite fit the groove around it.
• Intros, breakdowns, and fade-outs, which are exactly the spots where producers love to tuck little effects and Easter eggs away.
• Synth or keyboard lines that sound more like signaling than like melody, especially anything cold and mechanical against a warmer backing.

If you catch a likely candidate, isolate it, slow it down if you can, and write out what you hear as dots and dashes. Then run those dots and dashes through a decoder to see whether they resolve into real letters or turn out to be pure Morse-flavored decoration. Half the fun is that some passages genuinely decode into words while others are just vibe — and you honestly can't always tell which until you check. It's the kind of puzzle that turns a familiar song into something new.

Why musicians keep reaching for it

There's a deeper reason Morse keeps resurfacing in music nearly two centuries after Samuel Morse and Alfred Vail devised it. It's a code built entirely from rhythm, and music is itself made of rhythm — the two speak the same underlying language. A Morse message can be layered into a beat without disrupting the groove, hidden in a spot where only an attentive or an informed listener will ever find it.

Morse also carries instant, powerful connotations: secrecy, distress, distance, wartime, the romance of old radio. Dropping a few dots and dashes into a track tells the listener "there's a message buried here" without a single spoken word. And for the artists who choose to encode something real — a title, a place, a name, or, in the astonishing Colombian case, an actual lifeline to prisoners in the jungle — there's the deep satisfaction of a message that travels with the song to millions of ears while staying completely invisible to almost all of them. That is the enduring magic of morse code in songs: it lets an artist broadcast a secret to the whole world and keep it, all at once.

A word on separating fact from fan theory

One caution before you go down the rabbit hole: the internet is full of claimed Morse code "messages" in songs that don't actually hold up. Fans are enthusiastic pattern-matchers, and a random synth arpeggio or a bit of studio noise can sound tantalizingly like dots and dashes without being anything at all. Confirmation bias does the rest — once someone tells you a beep spells a word, it's very hard to un-hear it.

The examples on this page are the ones that stand on solid ground. Rush's "YYZ" is confirmed by the band and decodes cleanly to the airport code. The Colombian "Better Days" operation was documented by the military, the ad agency behind it, and mainstream news outlets, with rescued hostages confirming it. Duran Duran's SOS figure is an acknowledged studio touch. When you find a new candidate yourself, apply the same test: does it decode into something meaningful and intentional, and is there a credible source confirming it, or are you just hearing shapes in the static? Keeping that skeptical habit makes the genuine finds far more satisfying — and saves you from repeating a myth as fact.
