Based on a real measured system or lineage, but the mapped interpretation depends on a model or derived octave relationship.

This entry is included because it is culturally or practitioner-relevant. Any therapeutic interpretation should be read as contextual and non-diagnostic.

Review the evidence model

111 Hz has been measured as a resonant frequency in several ancient megalithic structures. Research by Dr. Ian Cook (UCLA) showed that exposure to 111 Hz shifts brain activity from the left prefrontal cortex to the right, associated with emotional processing and intuition.
