The Cosmic Octave

The vision of a symphonic planetary concert ignited a spark in mathematician and music researcher Hans Cousto on October 2, 1978. He had the brilliant idea of representing astronomical periods in tones based on the musical octave. His ingenious method, which involves multiple frequency doublings, became known as the "Cosmic Octave."

Vibration and resonance

The phenomenon of vibration manifests in all areas of existence. It encompasses the macrocosm of stars, planets, and moons, as well as rhythms, sounds, and colors. Even the microcosm of atoms and molecules is characterized by continuously repeating movements.

Vibrations generate resonance; they transmit and stimulate further vibrations (lat. resonare = to resound). In a sound, overtones resonate with the fundamental frequency, with the first and strongest overtone having twice the frequency. This natural law is the basis of all musical cultures. In Western culture, the ratio of one to double the frequency is known as an "octave."

The octave tone of the earth's rotation

The first tone determined by Hans Cousto is a high octave of the Earth's rotational frequency. This is how he calculated it:

The duration of the earth's rotation from the sun's highest point to its highest point again 24 hours later is

1 day = 24 hours á 60 minutes á 60 seconds = 86400 seconds

The frequency is 1 divided by the time.

1 : 86 400 seconds = 0.000 011 574 Hz (Hertz = vibrations per second)

Doubling this frequency up to the middle hearing range results in

0.000 011 574 Hz x 2 to the power of 24 = 194.18 Hz (2 to the power of 24 means 24-fold doubling).


Planetary periods, especially those of the Earth and Moon, are the timekeepers of our internal clocks. It is advisable to attune oneself to the natural planetary rhythms. Planetware's online shop offers practical instruments for applying the Cosmic Octave in the home, as well as in the fields of wellness, therapy, research, music, and art.
