Why Use Tuning Forks in Sound Therapy?
A tuning fork is designed to emit a precise single frequency (technically referred to as a 'pure' sound, being devoid of harmonics). Tuning forks are used in medicine, music, and science for a variety of applications. Their accuracy makes them ideal for use in sound therapy, using the human body's capacity to resonate with sound.
The creators of INNER SOUND, Arden and Jack Wilken, have developed sets of tuning forks spaced in pure 5th intervals for use at the ears.
The Pure Fifth
A pure 5th interval 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 considered the most important interval in sound therapy and frequently appears in music compositions, ancient and modern, due to its soothing effect.
The use of tuning forks, sounding a series of pure fifths, helps promote an organizing movement of expansion and contraction familiar to our whole organism, resulting in a state of deep relaxation, routinely experienced by clients.
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 subtle energy system or electromagnetic field. In professional practice, they are ideal to support any therapy or techniques such as massage, body work or energy balancing. Both practitioners and clients frequently find them helpful for managing stress or improving mood.
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.
Instruction booklet describing use & application provided with this set only covers personal use.
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 set.
The OM Tuners are based on the OM frequency (136.1 Hz) and a 5th below and above this frequency.
Instruction booklet describing use & application provided with each 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 set.
The Pair 5 set resonates most typically in the upper torso region, particularly the 4th energy matrix (heart chakra & 4th layer of the electromagnetic field). They help alleviate and/or manage any type of physical or emotional discomfort.

Price per set: £90.00
All sets of Inner Sound Tuning Forks are used at the ears for promoting stress reduction & relaxation in different regions of the whole organism.
