What do small rocks have to do with sound?* Nothing, really. I reference them in passing in the zine: ‘I could stare at a rock for solid 30 minutes, easy,’ I claim. This piece is an invitation for you to surrender everything and stare at a rock for an undisclosed amount of time. Pick one and gently flip the hour glass**. Feel free to hold the rock in your hand. Although they are arguably not as pretty when dry, please resist the urge to wet them.
If you find yourself waiting, here are some rock facts to pass the time until it’s your turn (compliments of various sources on the internet, none of which will be vetted, let alone cited):
- Rocks are Silicate-materials.
- They have a density of around 2200 kg/m^3.
- Sound travels through rock in the form of longitudinal, transverse and elastic waves.
- The speed of sound through solid rock is generally around 6,000 meters per second.
- The natural frequency of rock and soil is about 37 KHz.
* There’s a pun in there somewhere?
** There’s a certain tragic meta-beauty in using sand to track the time spent looking at a rock, no? Sand being the end result of the effect of time on rocks and all.
