The Cosmic Octave

The harmony between life and the cycles of the cosmos, rhythms, sounds, colours, atoms and essentially everything is the central theme at Planetware.
Kosmische Oktave

In 1978 Hans Cousto, a Swiss mathematician and musicologist discovered the natural law of the COSMIC OCTAVE as the link between different kinds of periodically occurring natural phenomena, such as the orbit of the planets, the weather, colors, rhythms and tones.

Using the formula of the Cosmic Octave f . 2n ( = multiple doubling of a certain frequency) Hans Cousto firstly transposed astromical periods into audible frequencies.

For example the first-ever Cosmic Octave calculation:

The octave-tone of the rotation of Earth:

The period: of the synodic day of Earth:
The period of the rotation of Earth around its own axis when the Sun is high in the south until it is high again next day.
1 day (24 hours . 60 minutes . 60 seconds = 86 400 seconds).

The frequency of the rotation of Earth around its own axis:
1 : 86 400 seconds = 0.000 011 574 Hz
(Hz = Hertz = cycle per second)

This frequency multiple doubled into the audible range:
0.000 011 574 Hz x 224 = 194.18 Hz
(224 means 24-fold doubling).

Tuning Forks
Today the Cosmic Octave is the basis for many holistic medical applications. It is origin to natural planetary tones, which directly correlate to the earth's natural life frequencies. These are utilized, for instance, in tone acupuncture using planetary tuning forks.

Tone acupuncture
Tone acupuncture is a beneficial deep cell massage at high frequencies to restore the body cells' natural resiliency. It permeates the entire body including inner organs, instantly resulting in deep relaxation and well being. Tuning forks can be self-applied at home, in the office, or during travel.

Hans Cousto
"The Cosmic Octave - Origin of Harmony"

The explorer of the formula of Cosmic Octave Hans Cousto offers a unique survey of a new scientific view of the world where a direct relationship has been proven to exist between musical tones, colors and the vibrations of the universe. The natural formula of the Cosmic Octave makes it possible to openly demonstrate the direct relationship of astronomical data, such as the frequencies of planatery orbits, to architectural works, ancient and modern measuring systems, the human body, music and medicine.

The book is widely published in Europe and now available through LifeRhythm, Mendocino, USA.
