What does sound do — to a room, a body, a mind? Cymatics, tuning systems, and the old harmonic traditions, read side by side with the physics of our time. Every idea traced to its source: measurement, tradition, or calculation.
Tesla famously said: "If you only knew the magnificence of the 3, 6 and 9, then you would have the key to the universe." What did he mean — and how does it connect to vibration, vortex mathematics, and modern frequency work?
The Solfeggio scale — six tones said by a modern tradition to unlock the secret potential of the human being. Where the claim comes from, and how to read it.
Where the "miracle frequency" actually comes from: the 1999 origin of the number, the one small study that exists, and the DNA claim nobody can source.
