Hemispheric Brain Sync | 6.5Hz + All 9 Solfeggio Tones

This track combines a 6.5Hz tone with all 9 Solfeggio frequencies, layered to support Hemispheric Brain Sync. Solfeggio tradition associates the full set of 9 tones with a broad range of effects across emotional and energetic states, while the 6.5Hz layer, sitting at the edge of Theta, supports a calm, receptive state conducive to whole-brain coordination. Return to this protocol during extended meditation or deep rest, to reinforce a balanced, synchronized mental state over time.
