The live symphony performances will take place in cities around the US and Canada. After starting in San Francisco on Sunday, the event will then travel to Austin, Texas in July.
The music and images are divided into five parts that correspond with different ecosystems: the sea, coastlines, land, mountains, and sky.
Images from each of those environments will be accompanied by a different chapter of music that's tailored to the ecosystem.
To put together the event, Nat Geo WILD worked with another National Geographic project called Photo Ark, which aims to photograph every species currently living in zoos and wildlife sanctuaries worldwide.

The previously unreleased photos include this remarkable image of three cuddly sea turtles...
... And this photo of a triumphant puffin bringing home a bounty of fish.
But unlike most nature programming, this one won't have a human narrator. "To be given the opportunity to create a symphony that guides the audience journey, rather than voiceover, is a rare challenge," Russell Emanuel, Bleeding Fingers’ CEO, said in a release.
National Geographic hopes the photos and music inspire more people to work towards protecting our planet.
