The Harmonic Frequency Derivations

Each of the eight chambers on the harmonic series encodes, through its Hebrew letter-value and a coupling factor, a specific frequency between the 111.2 Hz fundamental and its eighth harmonic at 889.6 Hz.

This is the theoretical heart of the Masters X Trilogy's distribution file: Andrew Chen's complete derivation of the harmonic stack. The claim is precise and falsifiable — any reader with the Hebrew values and the coupling method can reproduce every frequency independently. The full derivation, the forty inversion frequencies, and the two cathedral cross-references are documented below.

For each nota, the Hebrew letter-value is taken as the harmonic index; the coupling factor — derived from the figure's geometry — scales the index against the fundamental; the result is normalized to the 111.2–889.6 Hz band.

The frequencies ascend from the 111.2 Hz fundamental to 889.6 Hz across the eight harmonics. Each is fixed in phase relation to the fundamental; it is this fixed relation, repeated across all eight, that constitutes the harmonic stack.

Moreau's journals record a counter-set of forty inversion frequencies — used to bring a candidate down out of reception, in reverse, at the end of a session. They are the descent, and they are as important as the harmonics themselves.

The derivation is confirmed against two independent medieval structures whose acoustic signatures were measured directly. Both fall within the tuning range of the fundamental — and both, the file argues, were built to it.
