HOW IT WORKS

Solfeggio frequencies are a set of ancient musical tones historically used in sacred chants and healing traditions. Each frequency is associated with a different aspect of wellbeing.

Binaural beats occur when two slightly different frequencies are played in each ear. Your brain perceives a third tone equal to the difference, which can influence your brainwave patterns. Headphones are recommended for the full Binaural effect.
