One sustained drone in E. One hour. Nothing else: no talking, no melody, no bells cutting in halfway through.
I made it as a bed for mantra practice, something to sit inside twice a day that does not ask for your attention. Every layer breathes on its own slow timing, so it never settles into an obvious loop and never pulls you back out.
Good for meditation, for reading, for falling asleep, or for any hour that needs the room to stop moving. Low volume is enough.
Tonic: E, 164.81 Hz.
I also built a free Android app for the practice itself: your own mantra, twice a day, a simple timer, six short lessons. No ads, no subscription.
