The Universe does not speak english it speaks vibration and those vibrations are sound and light. That is all there is.
Did you know that pure sound within the range of 7 - 8hz can entrain our brainwaves into the Alpha range? This is a receptive expansive state broadcasting serenity, an antidote to anxiety and stress. This may be because we are then in alignment to the Earth's heartbeat.
At any given moment about 2000 thunderstorms roll over Earth, producing some 50 flashes of lightning every second. Each lightning burst creates electromagnetic waves that begin to circle around Earth captured between Earth's surface and a boundary about 60 miles up. Some of the waves - if they have just the right wavelength - combine, increasing in strength, to create a repeating atmospheric heartbeat known as the Schumann resonance.
The waves created by lightning oscillate with regions of greater energy and lesser energy. These waves remain trapped inside an atmospheric ceiling created by the lower edge of the "ionosphere" - a part of the atmosphere filled with charged particles. In this case, the sweet spot for resonance requires the wave to be as long (or twice, three times as long, etc) as the circumference of Earth. This is an extremely low frequency wave that can be as low as 8hz. As this wave flows around Earth, it hits itself again at the perfect spot such that the crests and troughs are aligned.
While they'd been predicted in 1952, Schumann resonances were first measured reliably in the early 1960s. Since then, scientists have discovered that variations in the resonances correspond to changes in the seasons, solar activity, activity in Earth's magnetic environment, (source NASA).
So two different tuning forks heard either side of the head that have a frequency difference of 7.83hz (e.g. 54.81hz & 62.64hz) will create Alpha brainwaves.
But so too will spending time in Nature.
