You’ve heard it. That slinky, late-night hotel lobby sound. It’s "Billie Bossa Nova." Honestly, when Billie Eilish dropped Happier Than Ever in 2021, this track stood out because it felt like a ghost of a 1960s Rio de Janeiro jazz club wandered into a modern pop studio.
But here is the thing. If you go looking for Billie Bossa Nova chords on a random tab site, you’re probably going to get a watered-down version. They’ll tell you it’s just A minor and E minor. Maybe a G thrown in for flavor.
Technically? Sure, you can play it that way. But it won't sound like Billie. It won't have that "something’s-about-to-happen" tension that Finneas baked into the production.
To actually play this song, you have to look past the "easy" labels. You need the extensions. You need the chromaticism. Most importantly, you need the right rhythm. Bossa nova isn't just a genre name here; it’s a specific mechanical way of playing the guitar or piano that dictates how those chords breathe.
The Harmonic Blueprint: What’s Actually Happening?
The song is officially in the key of Bb Major (though it leans heavily into its relative G minor/C minor vibes depending on how you analyze the movement). If you’re playing it with a capo—which most guitarists do to keep things manageable—you’ll usually park that capo on the 3rd fret.
When you do that, the "shapes" you play are Am7 and Em7. But let's get specific.

The Core Progression
Most of the song rotates through a cycle that feels circular. It never quite "lands" on a resolving chord for long, which is a classic bossa trick.
- Am7 (Am9 / Am13): This is your starting point. In the verse, you aren't just strumming a block chord. You’re plucking the bass note (Open A string) and then snapping the higher strings.
- Em7 (or Em9): This provides the "low" anchor.
- G (The Pivot): Sometimes used as a passing chord to get back to the top.
In the official sheet music, you’ll see more complex labels like Cm7, Cm6, and Gm(add9). Don't let those scare you. A Cm6 is basically just a C minor chord with an added "A" note. That one note—the major 6th—is the "secret sauce" of the bossa sound. It adds a bit of sunlight to a dark minor chord.
Why Your Strumming is Killing the Vibe
You can’t just "strum" Billie Bossa Nova. If you use a pick and go up-down-up-down, you’ve already lost.
Bossa nova is about the independent thumb. Think of your thumb as the bass player and your fingers as the drummer. Your thumb should hit the root note on the 1 and the 3. Your fingers (index, middle, and ring) pluck the rest of the chord on the syncopated "off" beats.
Basically, it’s a "pulse."

- The Thumb: Hits the A string (for Am) then the E string (for Em).
- The Fingers: Pluck the D, G, and B strings together.
If you listen closely to the studio recording, there is a "percussive slap" in there too. Finneas and Billie are big on texture. You want to mute the strings with the palm of your hand right after plucking to get that "stop-start" feel. It’s nervous. It’s intimate. It’s exactly what the lyrics are about—hiding in a lobby, being "not sentimental," and keeping secrets.
The Theory: Why These Chords Work
Music theorists often argue about whether this is "true" bossa nova. Purists might say it’s "Bossa-adjacent" pop.
Why? Because traditional Brazilian bossa nova (think Antônio Carlos Jobim or João Gilberto) uses incredibly dense jazz harmony—diminished chords, b5 subs, and complex turnarounds. Billie’s version simplifies this for a pop audience but keeps the tonal vocabulary.
Using a minor 9th chord instead of a plain minor chord changes the whole mood. A minor chord is sad. A minor 9th chord is "expensive." It sounds like a rainy night in a city you don’t live in.
The "Hidden" Chords
If you want to play the "pro" version, look for the B major 7 voicing used at the very end of some phrasing cycles. It’s a chromatic shift that feels like a "lift."

Common Mistakes to Avoid
- Playing it too fast: The BPM sits around 110–113. If you rush it, the syncopation loses its "swing." Bossa should feel like it’s leaning back in a chair.
- Ignoring the Bass Line: If you're on piano, don't just play the chords in your right hand. That alternating bass (Root to 5th) in the left hand is what makes it dance.
- Heavy Handedness: This is "whisper pop." Your playing should be as quiet as Billie’s vocals. Lighten your touch.
How to Master It This Week
Don't try to learn the whole song in one go. Start with the Am7 to Em7 switch.
- Step 1: Get your capo on the 3rd fret.
- Step 2: Practice the "Thumb-Pluck-Slap" rhythm on just the Am7.
- Step 3: Once your thumb is moving automatically, add the Em7.
- Step 4: Record yourself. Listen for the "space" between the notes. If there’s no silence, you’re playing too much.
Honestly, the beauty of Billie Bossa Nova chords isn't in how many notes you play, but in how you let the rhythm carry the melody. It’s a masterclass in "less is more."
Once you’ve got the basic pulse down, try experimenting with sliding your finger up the neck for the transitions. It adds a "human" squeak that fits the lo-fi aesthetic of the track perfectly.
To take this further, try playing along with the instrumental version of the track. It’ll force you to stay in the pocket without relying on the vocals to tell you where the "one" is. Focus on the interplay between the bass and the snare—or in your case, your thumb and your fingers. You’ll find that the more you relax your grip, the more "Brazilian" it starts to sound.
Grab your guitar, set the metronome to 112, and stop overthinking the fingerings. The vibe is the priority.
