Why does some dune sand squeak when you walk on it while other dune sand does not squeak?
The music is caused by friction from the sand grains rubbing against each other as we apply weight through our footsteps as we scoot our feet through the sand. However, there are certain conditions to be met. The type of sand that squeaks is usually a silicate, a feldspar, or a carbonate, the grains must be rounded (no sharp corners or edges), they should be around 300 micrometers in diameter, and they squeak best when they are dry (moisture on the grains acts as a lubricant, decreasing the friction).
