WHY DO THE DUNES SING

Dune singing, an amazing phenomenon produced by some deserts around the world, occurs when sand slides down the surface of dunes due to the action of the wind. The sand particles, as they roll downhill, generate a vibration that produces a distinctive, thunderous sound. This phenomenon does not occur in all dunes; it depends on the composition and size of the sand grains.

The eventual avalanche of sand is responsible for the resonant roar or the soft musical notes. For the singing to occur, the sand must be sufficiently dry, and it is the collision of the grains, the air and the disturbance caused by the wind or human activity that gives rise to this unique phenomenon.

The resulting sound can range from a soft murmur to a higher, shrill tone. As the wind caresses the crests of the dunes, sand particles collide and slide, creating a unique symphony in the middle of the desert. The hum can be barely perceptible and can sometimes be heard up to 10 km away. 

This mysterious concert of nature has captivated scientists and visitors alike, offering a unique auditory experience in harmony with the majesty of the singing dunes.

In 2012, a group of researchers revealed that it is not only the movement of the sand that determines the purity of the tones; the size of the grains also plays a role, although it is still unknown why this factor is so important. The variation in size causes the sand streams to flow at different speeds, resulting in a wide range of notes.

When the grains are of similar size, the sand streams within the avalanche move at more uniform speeds, producing more specific tones. However, scientists still do not understand how the irregular movement of the grains translates into sounds coherent enough to resemble musical notes.
