The astronomical periods of the Earth and Moon dictate the fundamental beat of life on our planet. For example, the Earth’s rotation shapes our sleep-wake rhythm and the biological growth and resting periods are determined by the seasons of the Earth’s orbit of the Sun.
In 1978 the Swiss mathematician and music researcher Hans Cousto applied the octave formula to the cycles of the Earth, Moon, planets and Sun to determine their respective notes. These notes correspond to our own biological oscillating frequencies.
Original Creations from the Developers of the Cosmic Octave
Whether for tuning an instrument or for sonopuncture, when it comes to resonances, frequency precision is of the utmost importance. That´s why Planetware’s tuning forks are made with the utmost precision from premium tool steel.
The tuning forks are available in 3 different types:
Difference in sizes of tuning forks 136.10 Hz:
|Total length||7.5 ''||8.1 ''||9.5 ''|
|Stem:||1.5 ''||2.2 ''||2.2 ''|
|Weight;||2.75 oz||3 oz||4.7 oz|
For occasional usage at home
Manufactured using highest quality nickel-plated steel with a surface as smooth as glass. The prongs are 4 x 8 mm with smoothly rounded edges joined to a handle with a thicker base.
They are heavier than other commercially available 440 Hz tuning forks and therefore resonate longer after being struck. Handcrafted and electronically calibrated at 20°C, the note precision with a tolerance of +/- 0.5 Cent (one semi-tone = 100 Cent) far exceeds the DIN (German Industry Norm) standard requirements. The audio frequency has been stamped onto the base.
With ergonomic grasp
An improved “S” tuning fork with the same prongs (and same note precision of +/- 0,5 Cent) 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.
For frequent usage
Intricately cut from a single piece of stainless steel and nickel-plated (a smooth matt finish). Prongs with chamfered edges all round. About 60% heavier than tuning forks "S" or "S≈plus", they resonate approximately twice as long and therefore do not have to be struck as often during prolonged professional use. Extremely high pitch precision of +/- 1 Cent (= 1 hundredths of a semitone). High-contrast inscription denoting the frequency and planet.
