Description
A tuning fork, or diapason, is a two-pronged metal fork that, when vibrated, produces a tone with a precisely known pitch. A tuning fork is constructed so that the tone produced depends very little on temperature and humidity. A good tuning fork produces very few overtones, and the sound approximates a pure sine wave. Some tuning forks have a sliding metal clamp so that notes other than the standard frequency (which is usually 440 or 880 Hz) can be played. The invention of the tuning fork is attributed to John Shore in 1711. A tuning fork is used to tune a musical instrument. The note of the musical instrument corresponding to the pitch is adjusted—tuned—so that it matches the pitch of the tuning fork. Singers sometimes use a tuning fork to strike the correct note. Most tuning forks are tuned to the chamber tone, a', with a frequency (currently) of 440 Hz. There are also tuning forks for other pitches, including pitches other than a1. To properly hear the soft tone of a tuning fork, the fork is held with the rounded end against the head (bone conduction) or mounted on a resonator or pressed against a tabletop, for example.

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 5th 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.
INNER SOUND Spiral of Fifths Tuning Forks The Spiral 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 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 5ths from the 1st to the 13th fork, at 4081.81 Hz.
The Effect of the Spiral of Pure 5ths
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.
Correct Way to HOLD Tuning Forks Always hold only the stem handle at the bottom of the fork. Touching the prongs will stop the vibration. See illustration below: Instructions for TONING the Tuning Forks There are several ways to tone your tuning forks: for the softest sound, tap tuning forks on a hard muscle such as the thigh near the knee or the firmest part of the palm of your hand for a slightly louder sound, tap gently on your knee cap or tap on the Tuning Fork Activator for a loud sound, strike with our Rubber Mallet for the loudest sound, very gently tap two tuning forks against each other or tap a single fork on the edge of a hard surface such as a table. Be careful not to nick them. Possible Ways to USE the Tuning Forks Tone a single fork or two forks together to create a harmonic and either hold or move above the body or place stem end on:
*any tissue of the body such as bones, organs and muscles
*acupuncture points or meridian energy lines (known as Sound puncture)
*reflex zones of feet, hands, ears or head
*chakras or transition points between chakras, front or back
*a crystal as you direct the crystal toward the recipient
*any vessel containing flower essences, gem elixirs, homeopathics, purified water, or any vibrational remedy
*planetary acupuncture points at various locations on planet Earth
*sweep through the subtle layers of energy field
*stroke meridians
*when toning two forks together, you can use to balance left/right, top/bottom, or front/back of the body
*move through a room to fill a space with a particular frequency
*move all around a person to clear discordant energies and fill their aura with a particular frequency These remarkable tuning forks are made of a special aluminum alloy that is heat-treated and is guaranteed to be accurate to .25%*. Each set and each individual fork comes in a protective wooden box for storage and travel. Aluminum Alloy tuning forks are designed for health and healing. Unlike stainless steel, they emit more pure, more vibrant, louder and longer lasting tones. And contrary to steel forks which create a single note, aluminum alloy forks are specifically designed to create rich overtones.Overtones are different octaves of the same note. The effect is similar to the Tibetan monks deeply moving chants. The rich overtones produced by aluminum alloy tuning forks create a deeper and richer experience. Overtones create an atmosphere where one can connect with their multi-dimensional essence.
