136.1 Hz - the tone of the Earth year
This tuning fork vibrates at 136.1 Hz. The pitch is calculated by transposing the time of the Earth's orbit around the Sun - one full year - into an audible tone, which is why it is called the Earth year tone. The same pitch is also linked with the Om sound known from Eastern tradition. Thanks to its deep, warm, calming ring it is one of the most frequently used tuning forks in sound therapy practice.
How to use it in everyday life
Using it is simple: tap the prongs gently against a rubbery surface or the pad of your palm, then hold the fork to your ear and listen to the pure, slowly fading tone. Many people use it as a starting signal for meditation, others to pace their breathing exercises or simply to wind down in the evening. You can pick it up for a minute or two at any time of day - it needs no preparation and travels anywhere with you.
Material and build
The body is made of blackened, nickel-free steel, so even people with sensitive skin can use it with confidence. The handle is warm-feeling maple wood, giving a comfortable, secure grip. The fork is 21.4 cm long and weighs just 74 grams - light enough for a pocket or bag. It is made in Germany with precise tuning.
Companions that match well
It belongs to the maker's series tuned to earth and moon tones, so you can later expand your collection with further forks - for example the 210.4 Hz moon tone - and play several tones one after another.
