Being the outcome of years of research, the book outlines the connection between music and the science of intonation, leading the reader through the ancient wisdom of Pythagoras, Fibonacci, Leonardo da Vinci, and Johannes Kepler, up to the most modern research of quantum physics and neuroscience.The author shows how the fixed tuning to A at 440 hertz was an arbitrary choice imposed by a few influential people, without providing any convincing reason or artistic proof to support it. This imposition has moved us away from the natural tuning of 432 Hz, which is linked to the earth's resonance.Thanks to this book, you will become aware of

which brain areas music activates and at which octaves of frequency the human brain operates;

what role sound waves play in modifying blood pressure, respiration, heartbeat, electrical resistance of the skin, neuroendocrine response, concentration, and other essential components for human well-being.

It is one of the most comprehensive works published on the subject of intonation.
