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!”
