The Voice Behind the Voices: How Jeongyeon Holds TWICE’s Sound Together

You know that feeling when a TWICE song just feels right — when the harmonies click, the emotion swells, and the chorus lifts you without you even knowing why? That’s Jeongyeon.

She’s not always in the centre. She’s not always in the spotlight. But if you stripped her out of the mix, you’d feel it. The blend would fall apart. The lift would collapse. Because Jeongyeon isn’t just another member of TWICE — she’s the voice behind the voices.

From their early tracks like Cheer Up and TT to the more mature sound of Feel Special and Moonlight Sunrise, Jeongyeon has been quietly laying the foundation. She doesn’t always get the flashiest lines, but her vocal fingerprint is all over their sound. And fans who know? They really know.

Ask any ONCE who’s been to a TWICE concert and they’ll tell you — watch Jeongyeon when someone else is singing lead. Her mouth’s still moving. She’s singing right along, matching harmonies like muscle memory. Not for show. For the music. She’s the glue.

And it’s not just about hitting notes. Jeongyeon brings warmth — a depth to the tone that fills the space under the melody. She’s the one making it rich without ever getting in the way. Take Depend on You, a fan favourite deep cut. The build-up in the chorus gets its emotional lift not just from the melody, but from Jeongyeon’s lower harmony locking in underneath. It gives the song guts. And soul.

Or listen to Up No More. That track hits hard for a lot of ONCEs, especially because of Jeongyeon’s personal connection to its meaning. But what people sometimes miss is how much of the emotion in that song comes from the blend — and she’s in that blend, from start to finish.

Even in live performances where other members are belting or dancing front and centre, Jeongyeon can often be seen, just off to the side, steady and focused. Mic close. Eyes on the others. Backing them up — literally.

A few fans have posted clips where she’s the only one singing the harmonies during high-energy numbers. She’s not just a singer — she’s a support system.

What’s wild is that she rarely gets credit for this. The casual listener hears a TWICE track and walks away humming the chorus. But they don’t realise why it hit so hard. They don’t hear the scaffolding behind the hook. The ones who do hear it? That’s a special kind of fan.

And when Jeongyeon had to step away temporarily for health reasons, the difference was felt. Not just by the group. Not just by ONCE. But by the sound. There was something missing. Something unspoken — a glue that holds the voices together.

She came back quieter, maybe more cautious, but she never lost that core. Still singing under the others. Still adding lift where it’s needed. Still holding the sound together.

There’s a reason veteran producers love working with people like her. You don’t have to ask. They just know. She hears it. She builds it. She holds the centre.

So next time you’re watching a TWICE stage or listening to a new comeback, try tuning your ear not just to the lead — but to the layer. The warm blend underneath. The part that doesn’t scream for attention but makes everything else possible.

That’s Jeongyeon. Harmony queen. Vocal backbone. The hidden heart of TWICE.
