Sound Therapy Glossary

432 Hz: Known as Verdi's A, an alternative tuning mathematically consistent with the universe, promoting deep calmness.
440 Hz: The current international standard tuning for music (ISO 16). Often criticized for being dissonant with natural human resonance.
Binaural Beats: An auditory illusion created when two slightly different frequencies are played in each ear, causing the brain to generate a third "beat" frequency.
Cymatics: The study of visible sound and vibration, often demonstrated by sand or water forming geometric patterns when exposed to specific frequencies.
Isochronic Tones: Regular beats of a single tone used alongside binaural beats to stimulate brainwave entrainment.
Schumann Resonance: The global electromagnetic resonance of the Earth, peaking at approximately 7.83 Hz.
Solfeggio Frequencies: An ancient six-tone scale (later expanded to 9) believed to hold profound spiritual and physical healing properties (e.g., 528 Hz, 396 Hz).
