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.
With different hearing ranges for different species, their harmonies are probably different. It’s like watching one of those videos of what a cat hears vs what you hear vs what a dog hears. The ratios between the notes in the full range may be different, so what is pleasant may be different.
Even for humans there are different tunings starting at different base frequencies. So like, maybe you need bird ears to hear the perfect harmonies they produce. Tho, most of the animal kingdom when vocalizing are just screaming “Fuck me!”
You and the other commenter are right, I don’t expect birds to be like “let’s both chirp and make a minor third interval”. I’m sure if they harmonized it would be for whatever sounds right based on how they evolved and learned.
What I’m getting at is it’s not harmonizing if they just happen to be making sounds at the same time. For the purposes of my question harmonizing is when we’re intentionally making two distinct tones simultaneously.
So two birds that are just chirping along their individual songs and they happen to overlap so they each chirp complimentary notes isn’t what I’m interested in. I want to know if any animals mean to harmonize.
