Hans Cousto

In 1978 the Swiss mathematician and musicologist HANS COUSTO 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 octave formula f x 2n (= n-fold doubled frequency), he calculated the tonal frequencies of the orbital and rotational periods of the earth, moon and planets, and later also the octave tones of various molecules.

Since that time Fritz Dobretzberger has been working closely with Hans Cousto. In 1989 he founded the company Planetware to inform about the Cosmic Octave and to offer tuning forks and other instruments for practical use.

All Planetware tuning forks are made from the highest quality steel to provide the most consistent vibration response with the highest frequency accuracy. The following description of the Planetware tuning forks allows a comparison to be made with other tuning forks available on the market.

This tuning forks are superb for precise attunement to the naturally ocurring frequencies of nature and life; they are used for tuning music instruments as well as in sonopuncture, which brings our body and soul into tune with the universe.



The Planetware tuning forks are available in different types

Tuning Forks "S-plus"
Tuning Fork S

Tuning Forks for occasional usage at home
• Made of nickel-plated high-quality special steel with a mirror-smooth surface.
• Fork arms of 4 x 8 mm with softly rounded edges
• Welded-on fork foot with thickened foot end
• Stamped frequency number on the tuning fork base
• Tuning accuracy of +/- 0,5 Cent (a semitone has 100 Cent)

Tuning Forks "S-plus"
Tuning Fork Splus with ergonomic handle

For a relaxed, ergonomic usage
An improved “S” tuning fork with the same prongs (and same note precision) but a longer and ergonomically designed soft grip handle making it easier and more comfortable to use during sonopuncture.
The soft grip is made of cork with a thermoplastic elastomer (TPE) coating.
On the side of one prong there is a high-contrast inscription denoting the fork model and pitch.

Stimmgabel S
Tuning Fork L

For frequent and professional usage
Intricately cut from a single piece of stainless steel and nickel-plated (a smooth matt finish). Prongs with chamfered edges all round.
They are about 60% heavier than the S version and resonate as long and therefore do not need to be struck as often during prolonged professional use.
Extremely high pitch precision of +/- 0.3% (= 0.3 hundredths of a semitone).
High-contrast inscription denoting the frequency and planet.

Stimmgabel S
Tuning Fork Lplus with ergonomic handle

For frequent and professional usage
Similar like the version L plus an ergonomic handle.
The ergonomically designed soft grip handle makes it easier and more comfortable to use the tuning forks during sonopuncture. The soft grip is made of cork with a thermoplastic elastomer (TPE) coating.

The Usage of the Planetary Tuning Forks
Sonopuncture

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 Tuning Forks should be in tune

The prongs of the “Splus” tuning fork resemble those of the “S” model; the vibration behaviour is identical as is the note precision. So the accuracy of the frequencies of all types of tuning forks offered by Planetware -— of course types "L" and "Lplus"as well — is high as possible. 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.


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.

Handling the tuning forks
Handhaltung

When striking the tuning fork, the thumb, forefinger and middle finger must be held on the shaft and the end of one fork arm must be struck with a swing from the wrist on an object. Do not touch the curvature of the fork with the fingers you are holding on to so that the fork arms can swing freely.

The tuning fork should not be struck on hard objects, otherwise an undesirable high overtone - a whistle tone - will be produced. Even with special tuning fork stop blocks made of hard rubber, which are available on the market, we have found this whistling sound in tests.

If the tuning fork is only rarely used, it can be struck at the ball of the other hand, for example.

Anschlagsrolle

If it is used more often, it is better to hit it on an object that has the softness of the ball of your hand. A guest towel that is rolled up tightly and tied at both ends with two cords is very suitable. After striking the tuning fork, the fork arms vibrate back and forth at the appropriate frequency. The back and forth movement of the fork arms is transferred into an up and down movement of the tuning fork handle via the lower curvature. By placing the stem of the vibrating tuning fork on the body, the vibration is transmitted there at its frequency.
