Evidence Levels
The atlas distinguishes what is measured, what is derived, what is practitioner-relevant, and what remains speculative. The point is not to flatten the field into one worldview. It is to make the status of each claim obvious.
Concert pitch, visible-light bands, and biological tempo references
Directly measured, standardized, or well-supported in mainstream scientific or technical literature.
Used when the atlas is describing a standard, a measured range, or a broadly accepted scientific reference.
Cousto-style octave mappings of orbital or rotational periods
Based on a real measured system or lineage, but the mapped interpretation depends on a model or derived octave relationship.
The underlying cycle is real, but the audible tone is a derived transposition used for comparison and practice.
Healing-frequency benefit claims around 432 Hz, 528 Hz, and related topics
Documented as a claim or emerging idea, but not established as a replicated scientific conclusion.
Recorded because users search for them, but not presented as settled evidence.
Historical or practitioner-significant lineages
Included because it has historical, cultural, or practitioner significance, not because it is settled modern science.
Reserved for entries whose value is cultural or traditional rather than modern scientific consensus.
Claim Types
A directly measured or standardized physical reference.
A note, tuning standard, or musical reference point.
A derived mapping from a measured cycle into an audible octave.
A frequency band used to describe EEG ranges or related neuroscience references.
A claim or usage pattern included because it matters in practice communities.
An instrument, resonance, or overtone reference used in sound work.
An interpretive or philosophical mapping layer rather than a direct measurement claim.
What The Labels Do Not Mean
An established measurement does not automatically imply a therapeutic outcome.
A theoretical mapping is not “false”; it means the interpretation depends on a model, such as octave transposition from a real cycle.
A speculative or practitioner-relevant entry is included for literacy and comparison, not as blanket endorsement.
The atlas is a research and practice tool. It is not a diagnostic device or a substitute for medical care.
