Solfeggio Carrier Tones for Deep Rest
10 Hours of 174 Hz Low-Frequency Tones Layered with Sub-Delta Pulse for Overnight Recovery

A full-night tone field built on the lowest Solfeggio frequency. A sustained 174 Hz carrier — long associated with grounding and pain relief in sound-therapy traditions — sits beneath a slow sub-delta pulse engineered to guide the brain into its deepest restorative stages.
No music, no narration, no swells. The carrier holds its pitch unbroken for ten hours so the nervous system never has to re-orient to a shifting signal.
Underneath the Solfeggio tone, a soft sub-bass bed supports parasympathetic dominance and slows breath and heart rate into overnight rhythm. The pulse is smoothed at the edges so it is felt rather than heard, keeping even sensitive listeners relaxed.
Perfect for chronic poor sleepers, burnout recovery protocols, nervous system regulation, overtrained athletes, shift workers, and anyone pursuing measurable sleep depth. Ten unbroken hours of Solfeggio-anchored sub-delta entrainment carry you from bedtime latency through morning lift without a single abrupt transition. Dim the lights, press play, and settle into the carrier.
