Sure, a coffee grinder is the perfect metronome for minimalism, just a steady thrum that keeps time like a metronome in a silent studio. I’d layer it with a thin sine wave and maybe a touch of reverse reverb to make it feel like a pulse, then add a subtle snare hit on the 8th beat just to keep the human touch. The only downside is that the grinder might complain if it knows it’s being turned into a sonic weapon, but hey, if you’re going to beat the espresso, you might as well make it interesting.
