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.
Oh hell yeah man. This would be a perfect moment to do some drugs if you’ve got some around. Then look at MC Escher’s art. And crystal structure. And those muslim temples with the crazy-complex geometric ceilings. The concept of target confusion ties into this. This is a really fun, really interesting aspect of the universe and cognition, this repetition, defocusing stuff. The effects a repeating pattern can have on the mind, through the senses. You can induce a spiritual experience by repeated stimulus or action. Like, a zebra’s stripes and an army squad’s jogging chant, and the crystalline structure of metal radio antennas are all utilizing the same mechanism: the de-localization effect of repeated structures. The way elements stop belonging to each piece and start becoming to the whole instead.
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.
