Do animals respond to music? And, if so, what could it tell us about their personalities?
Laurel Braitman, a science historian and author, has taken the slightly surreal step of organising live music in zoos to try to help answer those questions.
She says the events have begun to shed light on the individuality of different animals.
She tells BBC Future how she envisions a future where we understand what is going on in an animal’s head, something she says throws up questions about our treatment of different species.
