C5 — octave frame
512.00 Hz · 2:1 above C4 = 256
The crown point begins the descending ladder with C5 at 512 Hz, represented as a 2:1 octave ratio above the chosen C4 = 256 Hz reference. The octave ratio is grounded in the Pythagorean harmonic account, but placing it at the crown is an editorial body-tuning image rather than an ancient anatomical attribution.

Iamblichus, Life of Pythagoras (primary_canonical)
Chapters XV and XXV discuss musical education, purification, and the ordering of the soul; chapter XXVI recounts the discovery of harmonic ratios and identifies diapason, diapente, and diatessaron. The text supports music-and-ratio doctrine, not a seven-point body coordinate map.

Burkert provides modern historical analysis of Pythagorean number, music, cosmology, and the limits of later doxographic accounts; it is used here to keep the body projection distinct from ancient evidence.
