Inventing a language that outsiders cannot understand must be interesting. Especially when the language involves no spoken words and only tunes. The Turkish village of Kusköy has created its own language by using high-pitched whistling techniques for inhabitants to communicate with one another across distances.

In this village located on rough and undulated terrain, the villagers can speak to each other in full sentences and even convey important messages across fields and valleys. They have even devised distinctive tunes for each individual’s names.

Will this unique language survive? The people of the village are now ensuring that the curriculum in schools includes this whistling language, to keep it alive.
