I've put coupled oscillation at the center of my thinking about music, mind, and human sociality. One reason for that is that it is a phenomenon that can happen in relatively simple physical systems. It doesn't require "intelligence" or even "intention" to bring about synchrony. Here's a demonstration:
If you put a series of out of phase metronomes on a movable surface, you will get a #Kuramoto model synchronization https://t.co/0yMaBarNEB pic.twitter.com/BnsMa80KFB— Massimo (@Rainmaker1973) May 30, 2017
In this case the oscillators (the metronomes) are coupled by the (movable) surface on which they all rest.
