The tone of the platonic year - 172.1 Hz
This tuning fork is tuned to 172.1 Hz, a tone derived from the platonic year known from astronomy - the slow circular motion of the Earth's axis over roughly 25,800 years. When struck, you will hear a deep, even, long-sustained hum that most people find distinctly calming.
How is it used in sound therapy?
The sound therapy tradition recommends this tone for quieting the mind and supporting serenity and clear, ordered thinking. It is a favoured tool in sound baths, relaxation sessions and meditation: the fork's soft, even tone helps turn the attention inwards and release everyday tension.
Nickel-free steel, maple handle
The fork is made in Germany from black oxide, nickel-free steel with a comfortable maple wood handle. It is 19.5 cm long and weighs only about 74 grams, so it will not tire your hand even during longer sessions. Careful manufacturing ensures precise, lasting tuning.
How to play it
Hold the fork by its maple handle and gently strike the prongs against the pad of your palm or a soft rubber mallet - never against metal or hard surfaces. Then hold it close to your ear and listen to the slowly fading tone. With a few minutes of practice you will use it confidently, even as a beginner.
