Why Use Tuning Forks in Sound Therapy?

A tuning fork is designed to precisely emit a single frequency (a pure sound). Tuning forks are used in medicine, music, and science for a variety of applications. Their precision makes them ideal for use in sound therapy, using the human body's capacity to resonate with pure sound.

The creators of INNER SOUND, Arden and Jack Wilken, have developed a special series of tuning forks spaced in pure 5th intervals for use at the ears.

The Pure Fifth

A pure 5th is the naturally tuned form of the musical interval known as the perfect 5th in which the frequency of the higher tone is exactly 1.5 times the frequency of the lower tone. The pure 5th is an important element in our environment, appearing frequently in the natural harmonic spectrum of the voice. It is also the most important interval in sound healing and appears almost always in healing music compositions, ancient as well as modern.

The use of tuning forks in this interval, one at each ear, produces an organized wave of expansion and contraction throughout the body. This occurs at all levels helping our body to relax deeply. This relaxed state helps our body to regenerate and our energy system to balance and align.

The Effect of INNER SOUND Tuning Forks - Spiral of Pure 5ths

The Spiral Set is a series of 13 precision-made (tuned to the 2nd decimal) aluminum tuning forks that provide a stable and exact series of pure 5th intervals.

The wide range of frequencies within this set facilitates working at all levels of the organism, in the body from the feet to the head and in the entire energy system to include the chakras, energy channels, and electromagnetic field (also known as the aura). In professional practice they are ideal to support any therapy or techniques such as massage, body work or energy healing. On a personal level they are excellent for managing stress.

INNER SOUND Spiral of Fifths Set

The Spiral Set contains 13 precision-made (tuned to the 2nd decimal) aluminum tuning forks

The base tone of the Spiral is taken from the Schumann Earth Cavity Frequency. The dominant frequency is approximately 7.865 Hz, well below the limit of human hearing, which begins at 20 Hz.
The first tuning fork, at 31.46 Hz, is 2 octaves above the Schumann Frequency. The tuning forks step up by pure 5th intervals from the 1st to the 13th fork, at 4081.81 Hz.

Instruction booklet describing use & application provided with this set only covers personal use.
If you plan to use this set with clients, we strongly recommend that you attend our
Basic Level 2-day training to learn how to use them in a therapeutic context.

Personal and OM Tuners

The Tuners are two sets of three tuning forks based on the pure 5th interval.

The Personal Tuners are the 6th, 7th, and 8th tuning forks in the Spiral of Pure 5ths.

The OM Tuners are based on the OM frequency (136.1 Hz) and a 5th below and above this frequency.
They are manufactured to the same specifications as the Spiral set.

Instruction booklet describing use & application provided with either set.

Price per set: £140.00

Pair 5 Tuners

The Pair 5 Tuners are the 5th and 6th tuning forks in the Spiral of Pure 5ths.

The Pair 5 set balances the upper torso region, particularly the 4th energy matrix (heart chakra & 4th layer of the electromagnetic field). They are effective for relief and/or management of any type of physical or emotional discomfort.
