Whale Songs: The Ocean's Lullaby

In the deep, humpback whales sing songs that travel farther than any voice on land. This episode listens from below the waves.

The science, gently

  • Humpback songs can last twenty minutes and be repeated, verse by verse, for hours.
  • Low whale notes can travel enormous distances through the sea, far beyond any shout in air.
  • Whales in the same region share a song that slowly changes through the season, like a tune passed along.

Wonder together

  • What would you sing, if your voice carried a hundred miles?
  • Who do you think the whale is singing to?
  • What is the deepest sound you can make, and where do you feel it?

Tonight's calm-down

Whale song is slow because the ocean is big. Make your out-breath a whale note: long, low, unhurried. Send one to someone you love. The night ocean will carry it.
