The Singing Sands: Dunes That Boom a Musical Note for Kilometres
Slide down the steep face of Sand Mountain in Nevada on a dry summer afternoon and the whole hillside answers back. For a few seconds the slope gives out a deep, organ-like note that seems to rise from the ground and hang in the air, low enough to buzz in the ribs. Press a palm flat against the sand and the sound is felt as much as heard, a slow throb travelling up through the grains into the hand. Hikers reach for the same comparisons every time: a drone, a moan, a distant cello, a low-flying propeller aircraft passing somewhere below the horizon. The dune is singing, and it has been unsettling travellers for at least seven centuries.
Somewhere around 1275, crossing the Badain Jaran dunes on the edge of the Gobi, Marco Polo described a desert that seemed inhabited. The air, he wrote, filled with the sound of instruments, drums and the clash of unseen armies. Travellers of his day blamed spirits of the sand, said to call men away from the caravan by name. Polo was not the only chronicler to set the sound down. Medieval Arab writers, Chinese chroniclers and desert nomads across three continents left the same testimony in their own words.
