Silbo Gomero: a whistle can carry words across a valley

It is more than a call to attract attention. Silbo Gomero is a communication system from the island of La Gomera that represents Spanish speech sounds through whistles. Canary Islands government material presents it as a practice that coexists with the spoken language: we do not need to imagine an entirely different vocabulary for every object. [1]

The landscape helps explain the context. The local portal describes whistles being used to communicate across distances, valleys and ravines. We are not assigning an automatic ability to everyone in the Canary Islands: this is a particular practice that people learn and pass on. Our illustration therefore presents an editorial scene, not a photographic account or the reconstruction of a historical event. [2]

The local account of practitioners also describes young people learning and using silbo. UNESCO recognition dates to 2009. That date concerns heritage inscription rather than the beginning of the practice. Treating the two as equivalent would turn a history passed down over time into a recent administrative invention. [3]

School teaching is part of that transmission. The preamble to the Canary Islands decree of 9 March 2026 recalls its regulated introduction in 1999 and describes silbo as a whistled substitute for Spanish speech sounds. It discusses both individual technical practice and choosing words and sentences that aid understanding: producing a sound and making a message clear are not identical activities. [4]

An example invented by our editors: two people need to explain where to meet. One offers only an attention-getting noise; the other has a shared system for forming the message. Which information is missing in the first case? This activity separates attracting attention from communicating words. We are not inventing a whistling alphabet to call Silbo Gomero or assigning this dialogue to real practitioners. [1][4]

For a second editorial activity, imagine a small exhibition with three spaces: landscape, practice and transmission. Place an illustrated valley in the first, a question about constructing a message in the second, and a teacher’s name in the third when a documented account identifies them. Do not let a beautiful landscape take over the entire story. Understanding a tradition also means looking for the contexts where people learn it and the people who choose to keep practising it. [2][1]
