This work tries to reproduce the Schumann resonances, a natural and permanent atmospheric phenomenon made up of spectral peaks in the extremely low frequency (ELF) range of the earth's electromagnetic field. These propagate around the Earth in the form of waves, including a fundamental frequency (7.83 Hz) and four main harmonics between 14 and 34 Hz.

If we compare this phenomenon with research in neuroscience, we can see that the same frequencies determine the human brain's rhythm: the fundamental is identical to the Alpha wavelengths emitted by the brain during deep relaxation or meditation, while the harmonics correspond to the range of Beta waves, produced during intense cognitive activity.

It is therefore clear that the brain reacts to the impulses of certain frequencies, since it uses its own series of vibrations to communicate with the rest of the body. Halfway between science and fiction, the idea of this piece is to imagine the possible connections that could exist between the frequencies produced by the earth and those emitted by the human brain, in search of some correlation between the two.
