The Whales are known to repeatedly produce sounds at variable frequencies. So that, this modulation of sounds is well known as the whale song. As a musician, I can say that these sounds seem to follow our musical scale very accurately.
Using sounds of blue whale, captured by advanced hydrophone, and wonderful underwater images filmed in Moorea island (French Polynesia), I had the opportunity to compose another original song around the amazing world of whales.
