Schumann Resonance 14.3Hz Second Harmonic sits in a narrow, purposeful register: fast enough to feel alert, steady enough to hold. Layered ambient textures, haunting bells and synthesized ornaments move underneath the underlying harmonic influence.

Where 14.3Hz Comes From

The Earth's ionosphere naturally resonates at a set of frequencies known as the Schumann Resonances, first predicted in the 1950s and measured ever since as electromagnetic activity generated by lightning circling the globe. The base frequency sits close to 7.83Hz; 14.3Hz is its second harmonic, roughly double the fundamental tone. If the physics interests you, our answer to what the Schumann Resonance actually is goes into more detail on how it was discovered and why it's often described as the planet's own rhythm.

What It's For

This track was tuned for periods of low energy and fatigue rather than for winding down at night. It sits alongside similar steady, low-demand soundscapes in our Low Energy/Tired section, where the aim is to give a tired mind something rhythmic to hold on to. Play it while studying, working through a task list, or any stretch where focus keeps slipping. It also works well as background during a stressful patch, since the tone stays even rather than dramatic.
