Frequency guide
A plain guide to frequencies.
Everything you need, in plain English, with no homework.
New to this? Good. This page gives you everything you need, in plain English, with no homework.
What a frequency is.
A frequency is how many times something repeats in one second. It is measured in hertz, written Hz. One hertz means once per second. A hummingbird's wings beat around fifty times per second, so about 50 Hz. That is all the word means.
How the devices work.
Switch on. Choose a number. That is the entire operation.
A TrueWave holds the exact number you chose, steady and clean. A Spectrum starts from your number and sends it through seventeen rings, each adding its own harmonic above it. You choose the note. The geometry writes the chord.
The numbers people talk about.
A few frequencies are famous, and it helps to know their stories.
7.83 Hz. The base of the Schumann resonance, the Earth's own electromagnetic frequency, measured in the space between the ground and the ionosphere and documented since 1952. The most famous number in this field.
432 Hz and 440 Hz. Two tunings of the musical note A. Modern orchestras standardized on 440 in the twentieth century; some musicians prefer the slightly lower 432 and a long debate has followed. It is a story about music history, and people enjoy exploring both.
The solfeggio tones. A set of frequencies, such as 528 Hz, drawn from an old musical scale and traditionally associated with meditation practice. The tradition is centuries old; people use these tones the way they use singing bowls.
None of these stories is a promise. They are the culture and history around the numbers, and half the enjoyment of a frequency device is exploring them yourself.
How to build a routine.
What we suggest to every new owner:
- Pick one number. 7.83 is where most people start, purely because its story is the best known.
- Pick one time of day. Evenings suit most people, as part of winding down.
- Run it ten to twenty minutes, with the device in your hand or set down beside you.
- Keep the same number for a week before changing anything. Routines beat experiments.
- Then explore. The range is yours.
There is no wrong number.
You cannot break anything, and you cannot choose badly. The device produces the frequency you set, precisely, whatever it is. Treat the dial the way you treat a radio: find what you like, and stay a while.
