A transdisciplinary investigation into whether proportional relationships between frequencies constitute a fundamental level of information organization — prior to any absolute frequency.
"In the beginning, there was one thing. So the thing stretched. And as it stretched, it wiggled. And when it wiggled, it understood it was one no more, because there was it and the wiggle. So she wiggled more..."

| # | Hypothesis |
|---|---|
| H1 | Harmonic structures exist in real-world signals |
| H2 | They are computationally learnable by ML |
| H3 | They are cross-modal (light, sound, movement, etc.) |
| H4 | They are biologically significant |
| H5 | They have affective correlates in humans |
| H6 | They structure symbolic representations (language, mathematics, art) |
Harmonic Beacon · Artefact
The experiential probe of HIT. A continuously excited string holds open the full natural harmonic series as a living acoustic field. Available as a 24/7 live stream.
Phideus · Research Instrument
An AI research program testing whether harmonic frequency ratios transfer across sensory modalities using contrastive cross-modal learning (VICReg). 84.1% reference performance in musical validations.
