Platform term.
Where it comes from
A TikTok feature inherited from Musical.ly, where singing along with another user was the original use and the name.
How it is actually used
The two videos play simultaneously, which makes it suited to reaction, harmony and call-and-response formats. Creators can disable duets on their posts, and whether they are enabled is a deliberate choice — leaving them on is an invitation to be remixed. Distinct from a stitch, which uses a clip sequentially rather than alongside.
Examples
- "duet this with your answer"
- "the duet chain got to six people"
- "duets are off on that one"
Can a brand use it? Safe for brands
Safe and one of the better organic reach mechanisms available, since every duet exposes the original to a new audience. Leaving duets enabled means accepting you cannot control the response.
