If you have two crystal tuning forks of the same pitch and you strike one, the other will also make sound. This is called＂sympathetic resonance＂. The second fork resonates with the first one, and makes sound itself as if somebody has struck it. Resonance occurs when the vibrations of one object reach out and set off vibrations in another object. If the two objects have closely similar frequencies and one is vibrated, the other object will also sound.

The intervals of the crystal tuning forks create a sympathetic resonance with the quality of Sacred Sound deep within us. So that its sound waves through you, touches where it is needed, and balances. The archetype begins to align our thoughts and physical body around its vibration, e.g. when the forks are tapped, it is quite common to observe the head and body move and adjust to the proportions of the sound.
