I’m going to let you start off with whatever bad rock puns you can think of. (Rolling Stones, rock music, uh whatever.) Done? Great! Okay, now let’s talk about the mysterious ringing rocks of Montana – and how you can grab some free sounds to use in your music right now, just in case you can’t make it out to the great American west at the moment.
Richard Devine, that lover of sound design who seems to be in all places in the sound nerd universe at once, has been out grabbing sounds of this natural marvel for us.
And they are really, really crazy. Like, you hit these rocks with a hammer, and instead of hearing the sound of – well, a rock hit with a hammer, as you’d expect – you get clanging, sonorous percussion that sounds like metal.
Geologists have written tomes on these things, which exist in a few rare corners of the world (also Bucks County, PA and Western Australia, for some reason).
But the Montana rocks are especially strange. Whereas some ringing rocks can be hauled off and (of course) turned into percussion instruments, the ones in Montana only ring when they’re left in the pile. (Take only field recordings, leave only footprints, evidently.) So this particular geologic formation rings partly because of the rocks themselves, but also because of the arrangement in which natural processes have left them.
