Duet
what it means
The format made reaction and collaboration native to the platform. Duet chains — people duetting duets — can run many layers deep.
A TikTok feature that places your video side by side with someone else's.
the origin story
A TikTok feature introduced in 2019, building on similar functionality in the earlier Musical.ly app.
It changed how content spread: instead of reposting, people built on top of each other's videos in a visible chain. Harmony videos, comedy responses and multi-part chains all came out of it, and the feature was widely copied by other platforms.
in the wild
Someone duetted it and added harmonies.
That's how the whole song took off.
There are six people in this one video.
It's a duet chain. It keeps going.
