Everyone knows the feeling. It’s a wedding reception. The chicken was okay, the open bar is just starting to hit, and then that guitar lick drops. You know the one. It’s sharp, clean, and immediately recognizable. Before Maurice White even opens his mouth to ask if you remember the twenty-first night of September, the dance floor is already full. It happens every single time. It's basically a law of physics at this point.
But have you ever actually stopped to think about why this specific song of Earth Wind and Fire has such a vice-grip on our collective DNA? It’s not just a disco track. Honestly, calling "September" disco is like calling a Wagyu steak "fast food." It’s a masterclass in arrangement, a mystery of nonsensical lyrics, and a weirdly specific date that has turned into a global holiday.
What’s With the 21st of September?
People have spent decades trying to find the deep, spiritual meaning behind that date. Was it a birthday? An anniversary? Some cosmic alignment?
The truth is much more boring, and yet, way more interesting. Allee Willis, who co-wrote the song with Maurice White and Al McKay, once admitted that there was no significance to the 21st at all. Maurice just liked the way it sounded. He tried "the 22nd," "the 23rd," and other variations, but "the 21st" had the best phonetics. It clipped perfectly against the rhythm.
That’s the thing about great songwriting. It isn't always about a profound diary entry. Sometimes it’s just about how a consonant hits a beat.
Willis actually struggled with the song at first. She was a serious songwriter, and she was getting driven crazy by the "ba-dee-ya" refrain. She kept asking Maurice what the hell "ba-dee-ya" meant. She wanted real words. She wanted a story. Maurice eventually told her the most important lesson in pop music history: "Never let the lyric get in the way of the groove."
He was right.
The "ba-dee-ya" part is the hook that everyone, regardless of what language they speak, can sing. It’s universal. If you go to a club in Tokyo or a bar in London, everyone knows the "ba-dee-ya" part. It’s pure emotion, stripped of the baggage of actual language.
The Production Magic You Probably Missed
If you listen to the song of Earth Wind and Fire on a good pair of headphones—not just through your phone speaker—you start to hear the layers. Most pop songs today are built on a loop. Not this. This thing is alive.
Al McKay’s guitar part is the engine. It’s a percussive, scratching style that defines the era. But look at the horns. The Phenix Horns were the secret weapon of the band. On "September," they don't just play chords; they act as a second vocal line. They punch through the mix.

Then you have Verdine White on bass.
Verdine doesn't just play the root notes. He’s dancing. If you isolate the bass track, it’s incredibly busy, yet it never feels cluttered. It’s syncopated in a way that makes your body move before your brain even realizes what’s happening. It’s a "push-pull" dynamic. The drums are steady, but the bass and horns are constantly leaping around the beat.
Why the Song Refuses to Die
Google Trends shows a massive spike every single year on September 21st. It’s become a digital phenomenon. There are Twitter accounts dedicated solely to posting the song on that day.
But it’s more than a meme.
Musicologists often point to the "Major 7th" chords used in the song. In plain English? These chords feel nostalgic and happy at the same time. It’s a "warm" sound. The song is written in A major, but it spends a lot of time hovering in a way that feels like it’s floating.
It’s also one of the few songs that is truly ageless. It doesn't feel like a "dusty oldie" to a 20-year-old, and it doesn't feel like "new-fangled noise" to a 70-year-old. It’s the ultimate bridge.
Common Misconceptions About the Meaning
Some fans have tried to link the song to the 1978 solstice. Others thought it was a tribute to a specific event in the civil rights movement. While Earth, Wind & Fire definitely leaned into Afro-centric themes and spirituality (just look at their album covers), "September" was designed to be a celebration of joy.
Maurice White was deeply into the idea of "positive energy." He wanted the music to lift people up. In the late 70s, the world was a bit of a mess—inflation, the aftermath of Vietnam, political scandals. Sound familiar? People needed an escape.
The lyrics describe a love that began in September and stayed strong through December. It’s a simple "remembering" song. It uses the change of seasons as a backdrop for a lasting connection.

"Our hearts were ringing / In the key that our souls were singing."
It’s cheesy if you read it on a page. It’s transcendental when you hear Maurice’s falsetto hit it.
How to Actually Listen to Earth, Wind & Fire
If "September" is your only entry point into the band, you’re missing out on a massive world of jazz-fusion and R&B. To understand the song of Earth Wind and Fire in its full context, you have to look at the album it appeared on: The Best of Earth, Wind & Fire, Vol. 1.
Wait, a "Best Of" album?
Yeah. Usually, a new hit song is released on a studio album. But "September" was a "bonus" track recorded specifically to help sell a greatest hits compilation in 1978. It was a marketing tactic that accidentally resulted in one of the greatest recordings of the 20th century.
If you want to go deeper, check out these tracks:
- "Fantasy" (for the sheer vocal range)
- "Serpentine Fire" (for the heavy funk)
- "Reasons" (the live version from Gratitude is widely considered one of the best live vocal performances ever recorded)
The band was massive. Sometimes they had 12 people on stage. They used pyrotechnics, magic tricks (literally, Doug Henning helped them with stage illusions), and elaborate costumes. They were a spectacle. But at the core was this insane level of musicianship.
The Legacy of the 21st Night
Allee Willis passed away in 2019, but she lived to see the song become a cornerstone of internet culture. She eventually embraced the "ba-dee-ya." She realized that the song belonged to the world now.
In 2020, the song was inducted into the Library of Congress National Recording Registry. It was officially deemed "culturally, historically, or aesthetically significant."

Most songs fade. They get tied to a specific year and eventually sound "dated." "September" sounds like it was recorded yesterday and forty years ago at the same time. It’s a "perfect" record because it doesn't try to be cool. It just tries to be joyful.
Actionable Takeaways for Music Lovers
If you're a musician or just a fan, there's a lot to learn from how this track was put together. Don't just let it be background noise.
- Analyze the "Ghost Notes": Listen to the percussion. There are cowbells, congas, and shakers buried in the mix that give it that "shimmer."
- The Power of Simplicity: Notice how the chorus is just three notes for the most part. It’s easy to remember, which is why it stays stuck in your head.
- Check Out the Covers: Everyone from Taylor Swift to Kirk Franklin has covered this song. Comparing the versions shows you just how strong the underlying melody is. Swift’s version is a slower, banjo-led folk take, while Franklin brings it back to its gospel roots.
- Support the Foundation: The Maurice White Foundation continues to work on Parkinson’s research, a disease Maurice fought for many years.
Understanding the song of Earth Wind and Fire means understanding that music is supposed to make you feel something. It doesn't always have to be deep. It doesn't always have to be "art" with a capital A. Sometimes, it just needs to be a "ba-dee-ya" in the middle of a warm September night.
Next time it comes on, don't just sit there. Get up. It’s literally what the song was built for.
How to Build Your Own EWF-Inspired Playlist
If you’re building a playlist for a party or just a long drive, don't just pile on the hits. You want to build a "vibe." Start with "September" to get the energy up. Then, transition into "Let’s Groove" for that 80s synth-funk feel. From there, drop the tempo slightly with "That’s the Way of the World." This gives people a breather before you hit them with the high-energy horns of "In the Stone."
The goal is to mimic the band’s own live sets. They knew how to control an audience’s heart rate. They were masters of the "peak and valley" structure.
Maurice White once said that he wanted the music to be a "service to humanity." When you see a whole room of strangers singing along to a song about a random Tuesday in September, it’s hard to argue that he didn't achieve exactly that. It's a rare piece of art that remains purely positive without being cloying. It's just... good.
And sometimes, that's more than enough.
