528Hz Weightless Shimmer

deep-sleep cosmic ambient, instrumental only, no vocals, no drums, extremely slow and weightless, sustained crystal singing bowls tuned around 528Hz, pure shimmering overtones, soft warm drone, sparse gentle five-note melody floating above the bed, very long gradual swells, wide spacious stereo field, smooth attack and release, no percussion, no rhythmic pulse, no sudden changes, tranquil high-fidelity production
