The 528Hz DNA repair is a musical product marketed as a healing aid to damaged DNA. The 528 Hz frequency is the third note of the ancient six-tone Solfeggio Scale.
Marketers of the product argue that listening to music at certain frequencies can cause DNA repair. They say that the note that vibrates at 528 Hz has an impact on water molecules around the DNA helix, causing the healing. According to the theory, human cells absorb the note vibrations via DNA. Energy and vibration is transferred to molecules, which open up the chromosomes, allowing the frequency to reach the DNA.
