Meet Shanthi, a 36-year-old Asian elephant at the Smithsonian's National Zoo who composes her own tunes on harmonicas, horns, or whatever else her keepers provide.
According to keepers:
She will use her trunk to cover anything with a hole in it and blow until it makes a sound -- and will often coax the objects to get different types of sounds from it. She taps objects with her trunk and flaps her ears against objects that make noise.
This video is a compilation of some her most recent work.
