Harmonic Divergence is an installation that uses both the physical and cultural vibrations of Schumann resonances as its material.
The installation will be open to the public prior to all LEAF live performances, and by appointment during the week of May 25th-29th.
The Schumann resonances are a set of spectrum peaks in the extremely low frequency portion of the Earth’s electromagnetic field spectrum. Schumann resonances are global electromagnetic resonances, generated and excited by lightning discharges in the cavity formed by the Earth’s surface and the ionosphere.
Harmonic Divergence transposes those values from the electromagnetic spectrum into audible tones that are calculated into spherical harmonics of the Schumann Resonances, and also visualizes the waveforms of the resulting tones. The intervals used are based on the work of composer David First.
The audible output of the custom software is binaural, with discrete sets of frequencies directed to each channel.The individual volumes of each of 6 harmonics of the fundamental frequency (7.83Hz.) are algorithmically mixed both sonically and visually, based on the measured variations of both amplitude and frequency drift of the Schumann resonances.
The audio subsystem consists of 2x Foundry F12’s, courtesy PS Audio. The Foundry series of subwoofers redefines what is possible in low-frequency reproduction. With the introduction of the Foundry F12, reference-grade bass is no longer limited by room size, placement constraints, or compromise. This allows for accurate reproduction of precise bands of very low audio frequencies.
Culturally, much discussion regarding Schumann Resonances refers to the widespread pseudo-scientific, New Age, and conspiracy narratives which some say misinterpret natural electromagnetic phenomena as signs of a “speeding of time” and of shifting global consciousness. These claims often allege that spikes in 7.83 Hz frequency indicate, cause, or reflect human energetic, spiritual, or physical changes. These narratives have grown popular in social media, blogs, and “high strangeness” communities as a way to connect personal unease with global events.
In times of uncertainty, we often turn to mysticism, magical thinking, and seek answers to our problems that give us a sense of control over our lives. This art installation uses technology, light and sound to foreground divergent ways of thinking — tools for making our way in the world — but provides no answers, no inherent meaning of its own.
