Harmonic Information Theory

"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..."
— Nicolás Echaniz

The ratio as the minimal unit of information

The proportional relationship between frequencies is the minimal carrier of information. Harmonic Information Theory follows that intuition across computation, perception, and orientation, tracing how ratio-structured relations shape learned representation in Phideus and harmonic conditions of experience in Beacon. The result is a research program in which harmonic structure becomes experimentally legible across physical, biological, affective, and symbolic domains.

Artefact Harmonic Beacon ƒ×n

"Making the interference pattern of the subtle audible in the material realm."

The experiential probe of HIT — the human leg of the research. Where Phideus works inside computation, the Beacon works inside the room and inside the body. A continuously excited string holds open the full natural harmonic series as a living acoustic field: not a drone, but a sustained interference pattern that listeners enter. People report melodies, voices, textures not explicitly in the source — the Beacon takes those reports seriously as evidence. In therapeutic settings it runs alongside PMP, opening new conditions for symbolic and affective work. Available as a 24/7 live stream.

Research instrument Phideus φ · AI

"Do frequency ratios constitute a universal informational language?"

An AI research program testing whether harmonic frequency ratios transfer across sensory modalities. Phideus asks whether shared ratio structure between domains enables cross-modal recognition — independently of timbre, instrument, or absolute pitch. Cross-modality is the testbed, not the objective. Named after Phidias, the Greek sculptor whose mastery of proportion defined classical form.

Mariano Fernández Méndez

Mariano Fernández Méndez is a researcher, writer, and developer with a transdisciplinary background spanning artificial intelligence, electronics, acoustics, information theory, semiotics, and the social study of technology. Working across these fields, he has developed an approach oriented toward connecting technical, conceptual, and epistemological questions within a shared horizon. A member of Asociación Civil AlterMundi, he was responsible for the final compilation, writing, and conceptual architecture of this work.

Within HIT, his contribution centers on organizing a transdisciplinary investigation into harmonic relations and their significance for understanding information, structure, and relation across diverse systems.

Nicolás Echaniz

Nicolás Echaniz is an author of the book, co-founder of Asociación Civil AlterMundi, a musician, and a researcher in the field of natural harmony. His work also spans community networks, free software, and sovereign technologies. He leads the conceptual and technical direction of the HIT project and created the harmonic Beacon, a device that brings the theory's hypotheses into the realm of physical vibration.

He is the author of the founding premise: "In the beginning, there was one thing. The thing stretched. And as it stretched, it wiggled." This formulation captures a central intuition of HIT: the passage from unity to movement as a generative act of information. His work brings together music, technology, and artificial intelligence to explore the harmonic structure of sound and meaning.
