Many sound practitioners use "The Solar Harmonic Spectrum" as their primary set for healing for both people and animals. This set includes all 8 notes found in the C major scientific scale.

The Harmonic Spectrum Set emanates the pure sounds and overtones incrementally to bring forth relaxation and order. The forks are used together create various intervals and energy patterns. This also creates a connection between the various energy centers and glands associated with them. 

The Fifth Interval

Dr. John Beaulieu outlines each interval’s unique effect on the mind, body and spirit in detail in his book, Human Tuning. He carefully researched each interval’s effect on his brain and body listening to each for hours on end, even in his sleep. 

The C 256 fork is played with another tone to make the desired interval. One of the most important intervals is the fifth interval, accessed by striking C 256 Hz and G 384 Hz together. The fifth interval is the ideal interval to use for nervous system balance among other things. When I’ve felt more anxious or stressed, I’ve listening to the fifth interval, one fork on each ear, and felt my nervous system relax immediately!

There are two ways to sound your tuning forks. The first way is to gently hold them by the stems and firmly tap the end of the tuning fork on your knees or a hockey puck. This will create a pure tone and is excellent for deep listening. Bring the two-prong part of the forks about an inch away from each ear and listen to the quality of tone. Remember that your tuning forks are musical instruments. The second way is to hold the tuning forks by the stems and gently tap them together on the side of the times  to create an audible sound with overtones. This sound is good for moving around the body in the energy field. You can adjust the volume by the strength of your tap. Experiment with getting different sounds. When you move the tuning forks quickly they will create a beautiful ringing overtone.

Includes 8 tuning forks and a beautiful velvet pouch and a free hockey puck activator!
