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).

Slip face of a sand dune?
role in formation of sand dunes (in sand dune: Formation and growth of dunes)...sand brought up the windward slope. When this depositional slope is steepened to the angle of repose of dry sand (about 32°), this angle is maintained and the added sand slips down the slope or slip face. When this happens, the dune form is in equilibrium, and the dune moves forward as a whole, sand being eroded from the windward side and deposited on the lee.
What Part of a sand dune is characterized by a pronounced slope?
The upwind direction of a sand dune has a gentle slope. A steep slope is on the downwind side. The pronounced slope of a sand dune is called a slip face. Sand erodes from the wind off the slip face. To learn more about sand dunes, visit http://www.tulane.edu/~sanelson/geol111/deserts.htm.
