The Solfeggio Frequencies are a “lost” set of harmonic tones that have been claimed to be beneficial to the mind and are receiving renewed interest of late, mainly by people interested in how they influence the mind.

Nikola Tesla was correct when he said "Our entire biological system, the brain and the Earth itself, work on the same frequencies." It's time to tune our biology and our consciousness to resonate with the fundamental harmonics of the universe
