An interesting video about a rare language of whistles on Aeon: A rare language of whistles echoes less and less across the island where it was born:
The language of whistles known as Silbo Gomero — or just el silbo (‘the whistle’) — was once heard widely throughout La Gomera, one of the smallest of the seven main Canary Islands off the Atlantic Coast of Africa. Now it is used only by a few remaining shepherds on the steep hills of La Gomera’s countryside.
A somehow touching video about the language. Also fascinating that it is taught in school. Check out the post/video for more.
