What does Duet mean?
A duet is a TikTok feature that puts your video side by side with someone else's.
"She made a duet with that singing video and sang the second voice. Now she's viral."
Duets are used for reactions, challenges, singing and jokes. The original video stays visible next to the new one. A stitch is similar, but there you put a clip of the original before your own video. Also read about reaction video and FYP.
