Result of years of research, this book shows the ties between music and science of intonation, leading the reader through the ancient wisdom of Pythagoras, Fibonacci, Leonardo da Vinci and Johannes Kepler, up to the most modern quantum physics and neuroscience.

The author shows how the reference sound for the basic tuning of musical instruments at 440 Hertz was an arbitrary choice. Imposed by few influential people, it drove us away from the natural tuning at 432 Hz, connected to the earth's resonance.

By reading this book, you will become aware of:

• which brain areas music activates and at which octaves of frequency the human brain fulfils its functions;
• the role played by sound waves in modifying blood pressure, breathing, heartbeat, electrical resistance of the skin, neuroendocrine response, concentration and other aspects which turn to be essential to human well-being.

This is the most complete work on 442 hertz intonation, also known as the Verdian pitch, as it was supported by Giuseppe Verdi.
