⚡ the Schumann resonance — the Earth's heartbeat under everything

The planet-ionosphere cavity rings at 7.83 Hz (Schumann, 1952), pumped
by every lightning strike on the globe. Below hearing, so it plays the
machine: a 7.83 Hz pulse forever breathing the Earth Echo's tone and
laying a planetary wow under the moon's — and octaved ×4 to 31.32 Hz,
a true sub humming beneath the drone voice. The one dial the world
never turns: it is the size of the Earth, and that does not change.

Over them sit the effects the world modulates: <b>reverb</b> (earthquakes open the void, room light sizes it), <b>delay</b> (your hand's Y feeds it, Mercury retrograde smears it), <b>saturation</b> (Delhi's air becomes grit, hard aspects add dissonance, wildfires burn it, hunger grinds beneath), and <b>glitch</b> (every Wikipedia edit on Earth, every light flash, every new wildfire fires a burst). Nothing to install; the planet plays a synth in your tab.</p>

It sits below human hearing, so it plays the <i>machine</i> instead of the ear: a 7.83 Hz pulse forever breathing the echo's tone and laying a second, planetary wow under the moon's — and, octaved up four times to <b>31.32 Hz</b>, it hums as a true sub beneath the drone voice. It is the one dial the world never turns, because it is the size of the Earth itself — and the Earth's size does not change.</p>
