The 639 Hz FA tone and its meaning
This tuning fork produces the FA tone of the Solfeggio scale at 639 Hz. Hz (hertz) tells you how many times the prongs vibrate per second - 639 Hz is a clear, moderately high, pleasant tone. According to the Solfeggio tradition, the FA tone stands for harmonious human relationships and better, more open communication, which is why many people choose this fork when they wish to tune into peaceful togetherness.
Nickel-free steel with a maple handle
The fork is made of black oxide, nickel-free steel, so it can be used with confidence even by people with sensitive skin. The pleasant maple wood handle gives a secure grip; the fork is 13 cm long and weighs only 74 grams. It is carefully manufactured in Germany, and its precise tuning lasts for many years.
How to play it
Hold the maple handle and gently tap the prongs against an activation pad or the soft part of your palm. Then hold the fork close to your ear and listen to the clear, softly fading tone. Tuning fork sounds are quiet and intimate - they come into their own in a silent environment, for example during evening wind-down or resting exercises.
