7.83Hz Schumann + 432Hz | Deep Earth Sleep | 共鳴 | Black Screen | 3:33:33

Enter a deep earth sleep field built around gentle Schumann-style movement and 432Hz-tuned harmonic air. This 3:33:33 Quiet Circuit environment is designed for sleep, meditation, quiet reading, and calm background listening. Instead of repeating a short finished loop, the sound evolves continuously through slow analog drift, unsynchronized oscillator movement, soft harmonic pressure, and occasional tape-like pitch settling. Sound design: 7.83Hz used as subtle modulation, not a sharp audible test tone 432Hz-tuned harmonic reference with warm 108Hz, 144Hz, and 216Hz body no vocals no lead melody continuous long-form evolution occasional slow pitch descent and recovery opening visual followed by a black screen Recommended for: deep sleep and nighttime listening meditation and breath practice quiet focus and reading low-distraction background ambience deep earth resonance atmosphere Listen at a low, comfortable volume. This audio is created for relaxation, focus, and atmosphere. It is not medical treatment and does not guarantee any physical or psychological effect. 日本語補足: 7.83Hzの揺らぎと432Hz基準の倍音を使った、睡眠・瞑想・静かな集中のための長時間アンビエントです。短い完成音の反復ではなく、複数の周期がずれながら連続的に変化します。ときどき時間が緩むような、ゆっくりしたピッチの沈み込みも加えています。小さめの音量でお聴きください。 #QuietCircuit #SchumannResonance #432Hz #DeepSleep #BlackScreen #AmbientMusic #MeditationMusic #共鳴 #AngelNumbers #333
