"Marine organ" that produces music from waves and wind

The structure singing in the video below is a long instrument 70 meters off the coast of Zadar in Croatia, which produces fascinating harmonies from the sea movements.
The project was designed in 2005 by architect Nikola Bašić, after a new pier was built to receive cruise ships and their tourists visiting the charming port cityOn its surface, the body looks like large marble steps leading to the Adriatic Sea.
 Below, however, is a series of narrow channels 35 which connect the organ pipes. Each set of stairs has five organ pipes and each is tuned to a different musical chord.
In the ways that the waves and the wind push air through the channels, a new song comes through the organ pipes and take care of the environment. The sounds produced are completely random, depending on the time, energy pressure waves of the sea.Visitors say that the sound is "frighteningly memorable" and "very rhythmic and even mesmerizing."
In 2006, the Sea Organ won the European Prize for Public Urban Space to be a "perfect grandstand for watching the sunset over the sea and the outline of the [neighboring] island of Ugljan, while listening to the musical compositions played by the sea itself . "
