174Hz Bilateral Sleep Music - Calm Your Nervous System & Stop Overthinking | Black Screen 3 Hours

🎧 Listen ad-free with your screen off: Spotify → https://open.spotify.com/playlist/40E... | Apple Music →   / synapt   Three hours of original bilateral sleep music, built around 174 Hz. A soft tone glides slowly from your left ear to your right and back, in the gentle left-right rhythm used in EMDR-style bilateral relaxation. It starts at an easy pace, then keeps slowing down as your body settles, to help calm a busy nervous system, quiet an overthinking mind and drift into deep sleep. 🎧 Headphones recommended: the left-right movement is the heart of this track. Speakers work too. 🌑 Follow the light for a few minutes, and close your eyes when they feel heavy. The screen fades to black after 15 minutes. How it is made: • The whole piece is tuned so that its home note is exactly 174 Hz (F), with a soft 174 Hz tone underneath. • Bilateral layer: one full left-right sweep takes 2.4 seconds at the start, 8 seconds after one hour and 16 seconds by the end. The light on screen moves in exact step with the sound. • For the first hour a soft bowl rings on each side at every turn. These fade out after 55 to 75 minutes. • A quiet binaural layer glides from 4 Hz down to 1 Hz (delta). • Slow warm chords, a few soft piano notes and a warm brown-noise bed swell at 6 breaths per minute. Let your breathing follow it. • Nothing loops: all 3 hours are composed from start to finish and get darker and quieter as the night goes on, with no sudden sounds. ⏱ Chapters 0:00 Follow the light · 174 Hz bilateral 15:00 Black screen · keep listening 55:00 The bowls fade, the sweep slows 1:15:00 Slow waves · deep rest 2:00:00 Deepest part of the night 🌙 New sleep frequencies every week → subscribe:    / @synaptsounds   Instagram:   / synaptsounds   Facebook: https://www.facebook.com/profile.php?...
