VIDEO: Native Inuit Throat Singers Reverberate Across Anchorage

Karin and Kathy Kettler, the Canadian throat-singing sisters who together are known as Nukariik, carry on the traditions of the elders from their mothers' village in Kangiqsualujjuaq, Nunavik, which is located in northern Quebec.

Throat singing started as a way for women to pass the time while men were out hunting. It's a friendly competition in which two women face each other and layer the same beat a second apart. As Kathy says, "It's easy to tell who wins at throat singing because the other person is usually laughing at you because you've lost."

It's also a way to sooth babies. Most women wore the babies on their backs in large hoods, allowing babies to feel throat-singing vibrations reverberating through the chest.
