Equal Temperament Tuning System
108 atlas referencesThe twelve-tone equal temperament reference used for note-frequency lookups throughout the atlas.
Standard equal-temperament note table with A4 = 440 Hz.
Research
Sources Library
This library shows the source families behind the atlas. Some entries point to standards or measured domains, some to Cousto reference tables, and some to practitioner lineages that are included for provenance rather than consensus.
How To Use This Page
Frequency Atlas does not treat every source type as equivalent. Standards and measured references carry a different weight than interpretive or practitioner literature.
Where the atlas cites a practitioner lineage, that is so users can trace where a claim comes from. It is not a statement that the claim has been clinically settled.
For the densest Cousto-derived material, use the tuning data reference alongside this library.
