Rather than getting of an article, I read it off of a comic of a couple’s honeymoon story. Basically it’s a architecture by architect Nikola Bašić with 35 pipes of different length that creates noise as the wave hits and pushes the inner air of the pipes. I thought it was a cool idea of using nature itself as an instrument, similar to how we use recording to create sounds.
The link for the youtube video of the sea organ playing is down below. It’s quite beautiful!
