Sleep Music · Fading Northern Lights & Brown Noise · 4 Hours

Four hours of sleep music under the northern lights: deep brown noise and slow singing bowl tones. Over the first hour the sound settles and the lights begin to fade, so the screen grows darker as you fall asleep. No AI-generated music, no looped clips, no stock footage. Sound and picture are played live by Frequency, a sound and light engine I designed. It follows rules I set, a bit like a music box that never repeats. The northern lights, the lake and the mountains are rendered in real time, not filmed. The sound breathes slowly, about four times a minute, and the curtains of light rise with every breath in. Each singing bowl tone sends a slow wave of light along the brightest curtain. The pulse comes from two low tones beating against each other, not from binaural beats, so speakers work just as well as headphones.
