Some animals sing (birds, whales) and plenty of animals make sounds together at roughly the same time (wolves howling, prairie dogs yelling at threats). Are there animals that harmonize? Or animals that make sound that’s rhythmically coordinated, like has a time signature?
Guess I’m asking about more finely coordinated sounds. It’s something that’s pretty neat about human music.
My first thought would be whales. No idea if they m correct though
