G4 — fifth tone

384.00 Hz · 3:2 diapente

The heart-region point uses G4 at 384 Hz, the 3:2 diapente ratio over the 256 Hz base. Iamblichus' ratio supports the harmonic label, while the heart placement is an editorial metaphor for concord and must not be read as an ancient cardiac or emotional prescription.

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.

Walter Burkert, Lore and Science in Ancient Pythagoreanism (scholarly_modern)

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.
