This listing includes a set of 5 brass tuning forks and cloth carrying case.

Note: These tuning forks are made of brass, which is a soft metal, great for harmonics and sound healing. Because of this softness, you might find the occasional small mark or scratch. The fork isn’t damaged, nor is the tuning off. It can happen during packing by the manufacturer, or during shipping and handling. We provide safe storage and great care when handling them.


The Bioresonance Set of 5 Brass Tuning Forks from PraPelnia Crafts were developed based on brain wave studies using EEG technology, mapping different states of consciousness known as Delta, Theta, Alpha, and Beta wave states of the mind. These forks are tuned to frequencies that help align the brain with these different states of consciousness.

By sounding one fork on the left ear and another on the right, the brain integrates the two differing tones to create a third, different tone called a binaural beat heard as a pulsation, gently signaling the brain to shift consciousness. Binaural beats heavily affect the brain and can be used for relaxation, pain relief, and inducing different states of consciousness.

This set includes the following tuning forks:

Delta - Deep Dreams, Leaving the Body - 258 Hz
Theta - Dreams, Deep Meditation, REM Phase - 262 Hz
Alpha - Relaxation, Wakefulness, Pre-Sleep, Sleepiness - 256 Hz
Beta - Activity, Thinking, Concentration, Cognitive Function - 269 Hz
Base Tuning Fork - 256 Hz
