The drone here is built from five detuned voices stacked wide, so it never sits still enough to become a single tone your ear can lock onto. That's the actual trick behind why it disappears after a minute. Underneath, brown noise does the heavy lifting and a slow, twelve-second reverb tail keeps the waves sounding like they're arriving from somewhere below the room rather than in it. No bell pattern to speak of, so there's nothing on a timer pulling your attention back up toward the surface.
This is deep sleep music built for the nights your brain won't stop running laps. Not a lighter white noise machine loop, but a low, moving wash meant to sit under the floor of your attention. If you've tried regular sleep sounds and still feel like you're floating just above sleep instead of in it, Abyss is the one built to actually pull you under.
Like everything on StillTune, none of it is a looped recording. The drone and waves are generated live and re-voice themselves slightly each time, so a full night never runs into an audible seam or a loop point the way a downloaded sleep-sound file eventually does.
