Whale Song is a collection of underwater recordings of humpback whales singing and calling in the Indian Ocean, off the coast of Madagascar. These soundscapes were recorded in pseudo-stereo with two hydrophones and also include the sounds of corals, fish, shrimp and water movement.

Humpback whales migrate to this part of the Indian Ocean every year to mate and give birth. Their fascinating songs and calls can be heard underwater from tens of miles away, however reaching this part of the world can prove quite challenging as seen in the second part of the teaser.

Humpback whales produce what is known as the most complex and beautiful sounds in the animal kingdom. Researchers aren't completely sure how they produce sound or what its purpose is. Their calls are potentially intended to communicate physical fitness when mating, to strengthen social bonds between individuals, to help humpback whales orientate themselves underwater through echolocation, or even purely for the whales' enjoyment and pleasure.

These mesmerizing recordings were captured over the course of two weeks. The waters around Madagascar are some of the cleanest and most biodiverse on the planet, with amazing density and variety of underwater wildlife. As a result the soundscape is busy and chaotic all year round. Humpback whales are indeed very loud, but their calls have to compete with a myriad other elements in the frequency spectrum.
