Harmonia

THE WIZARDRY IN THE FREQUENCIES

From the Earth’s field to a single note, and from that note to music

1. 01The Field

   33,563 nT

   The International Geomagnetic Reference Field (IGRF-14) puts Earth’s magnetic field over San José at 33,563 nanotesla. That one measurement sets every pitch you hear.

2. 02The Note

   1,428.991 Hz

   Protons precess at 42.576 Hz for every microtesla of field — one of the most precisely known constants in physics. 33.563 µT × 42.576 = 1,428.991 Hz: the tone a proton magnetometer hears from a bottle of water in San José.

3. 03The Root

   89.312 Hz

   Halve it four times — four perfect octaves — and you reach 89.312 Hz. Everything is built upward from this root, so the proton tone lives inside every chord as its sixteenth harmonic.

4. 04The Harmony

   2 and 3

   Only the numbers 2 and 3 are allowed: octaves (2:1), fifths (3:2) and fourths (4:3), the ratios of the Pythagorean tetractys, 1 + 2 + 3 + 4. No equal temperament and no rounding, so the overtones of each chord coincide exactly instead of beating against one another.

5. 05The Bell

   T2* ≈ 1 s

   A pure tone rings at exactly 1,428.991 Hz and fades over about a second — the same decaying signal a proton magnetometer records. Fed into the Harmonia instrument’s own analysis software, the track reads back Earth’s field as 33,564 nT.

6. 06The Rhythm

   6 s · 12 s

   Magnetic Master moves in 6-second cycles — polarize, then listen — the measuring cycle of the instrument. The Meditation slows to a 12-second breath: four seconds in, eight seconds out, five breaths a minute.
