E4 — third tone
324.00 Hz · 81:64
The lower-abdominal point carries E4 at 324 Hz, the 81:64 ratio used in this reconstructed ladder. The coordinate simply spaces the seven tones down the silhouette and does not claim that Pythagorean sources link this interval to the lower abdomen or to a health effect.

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.
