The same thirty-six decans, derived into sound. The visual register takes the planet's kamea and discards the grid, keeping only its order number as a count of sides. The acoustic register keeps the grid and traces it — the same path that draws the Agrippan sigil, read as melody.
Atom = the Chaldean ruler's melody · in the planetary mode of the triplicity-ascent Room lord · in the key of the sign lord's domain.
Exaltation and fall always oppose, and therefore sit a tritone apart. The only mode in which both sound is the mode whose unique tritone they occupy. Eleven seats resolve uniquely; Virgo takes Lydian by pip testimony — so Locrian is seated by no lord.
Trace 1 → n² through the planet's magic square; the column is the scale degree, n the meter, the row spent on register. The phrase span is constant, so density follows n² — Saturn deposits nine slow notes where the Moon deposits eighty-one fast ones.
Both registers, thirty-six each. The house register carries the Chaldean seam: for Gemini II rising exactly seven cells slip, contiguous from Aries I. Seam Atoms are marked ✧.
The key structures fall out of the compositions: the luminaries sound pure augmented triads, Mars and Jupiter the combined light, Venus, Mercury and Saturn the lightless hexachord. In the personal register every Word re-voices — the Atom is the only transposing unit; the Word is irreducibly personal.
