The Cosmic Octave
In 1978 Hans Cousto, a Swiss mathematician and musicologist discovered the natural law of the "Cosmic Octave"; this links a variety of natural phenomena which occur periodically, such as of the orbits and rotations of the planets, the weather, colours and musical rhythms and tones. Using the formula f (frequency) x 2n (= doubled n times) he calculated the audio frequencies of the circulations and rotations of the earth, the moon and the planets. In musical theory the octave is well known: if you double the "hertz" (cycle per second) of eg middle C on the piano, you reach C one octave higher, if you halve it, C one octave lower is attained.

Since 1978 Fritz Dobretzberger has cooperated with Hans Cousto, producing tuning forks which vibrate at the frequencies calculated, thereby making these audible. Eleven years later he founded Planetware to provide information about the Cosmic Octave and to ensure that the relevant instruments are available for everyday use.
The Usage of Tuning Forks
In order to allow people to hear and experience the planetary frequencies, we commissioned tuning forks to be manufactured. Nowadays such tuning forks are used in sonopuncture (phonophoresis). With this application the handling of tuning forks has changed. Unlike when tuning musical instruments, the tuning forks used in sonopuncture are held much longer. Often they are placed on the body for minutes after being struck and when the vibration has stopped they are struck anew and again placed on the body. This process is repeated a number of times.
A WORLD FIRST: The “S≈plus” tuning fork with its ergonomically designed handle
After more than 30 years interest in the planetary tuning forks for use in sonopuncture has increased so dramatically that Planetware has been able to develop tuning forks with an ergonomically designed handle. The shape and material used allow the tuning fork to be held more easily and comfortably than ever before. The easy handling means that your fingers don’t tire or cramp as quickly.
This innovative ergonomic soft grip is the result of years of research and testing with various materials and shapes. It has been tried and tested by the users themselves.
A Tuning Fork Should Be In Tune (High-grade Steel vs. Aluminium)
Whether for tuning or sonopuncture, the highest possible resonance is of the utmost importance for frequency precision. Planetware's tuning forks, made of high-quality stainless steel, offer this high precision.
Compared with aluminium tuning forks, those made of stainless steel have a more stable frequency deviation arising from temperature differences, which is especially important in their use in sonopuncture. During this process tuning forks are held in the hand for longer periods leading to their heating up. The change in frequency in stainless steel tuning forks caused by this temperature difference is minimal compared to that produced in aluminium tuning forks that expand more when heated, thus changing the note.
Since the autumn of 1978 when Hans Cousto identified the frequencies of the Earth, moon, planets and sun we have placed great value on the highest quality. A short anecdote from those days serves as proof: The first tuning forks delivered from the factory were only of DIN standard meaning some forks had a deviance of up to 1 Hz from the specified frequency. We returned these tuning forks assuring the manufacturers that a difference of 1 Hz in the octave of the Earth’s rotation would make the terrestrial day approx. 7 minutes shorter than it actually is (in fact, in the past 3000 years the length of the Earth day has increased by approx. 0.05 seconds).
In order to achieve this high quality and uniform vibration behaviour all PLANETWARE tuning forks are made from stainless steel of the highest quality. Furthermore, each fork is individually hand-filed as often as necessary (either at the ends of the prongs or the inside of the base and at a temperature of 20°C) to achieve the required precision.
The better the frequencies harmonize, the better the vibrations are transmitted. Nowadays there are a number of companies on the market offering tuning forks. If you are looking for high quality, check out the accuracy of the frequency.
