From frogs chirping through the night to whales humming across the oceans, nature is full of fantastic music. Not all of it sounds pleasant to the human ear, of course (the droning of cicadas can cause ear damage at close range, and even crickets can wear out their welcome), but it's hard not to admire the way animals make such complex and astounding noises.
There's more to animal calls than just taking a deep breath and hollering. Some animals play their bodies like instruments, and others make sounds that humans need machines to pick up. To highlight some of this diversity, we've compiled a list of 7 unusual animal sounds, some of which make music that seems almost... philharmonic.
