Got an example? Don’t get what you’re talking about. Thanks.
Thinking about it more, I probably should have said “doubling” for two dancers, and “chorus” for more.
In any case for visual doubling, something like this: https://youtube.com/shorts/ZBgeuMJA3vA?si=MPa6AG6q-xw0cutC
For aural doubling here’s an example (not great but first passable example I found) https://youtu.be/kFaaGwAsGt4?si=mfjHIl5PtufoYriK&t=42
Basically, in audio recording if you have two similar but slightly different takes, it adds sparkle to the sound, it makes it seem bigger. Similarly with these sorts of tik tok dancers (to me) it has a similar impact, but visually instead of audibly.
Background dancers are often called a chorus:
I could be mistaken but I thought they got their name from actually singing too? I believe the name for the “chorus” effect in audio recording comes from that experience - hearing the sound of a group of people singing instead of one person singing. Regardless, the name is appropriate.
