Harmonic Monochord Ratios & Epigraphy

The acoustic foundations of Pythagorean number theory derived from string division ratios:

1:1

Unison (Fundamental)

Whole string · The Monad / Undivided Unity

2:1

Octave (Diapason)

Half string · The Dyad / Doubling of pitch

3:2

Fifth (Diapente)

Two-thirds length · The Triad / Consonant harmony

4:3

Fourth (Diatessaron)

Three-quarters length · The Tetrad / Acoustic boundary

“
And indeed all things that are known have number; for it is not possible that anything could be either comprehended or known without this.
— Philolaus of Croton, Fragment B4 (c. 470–385 BCE)

Calculation Conventions & Privacy Principles

OmniZodiac uses the Period Reduction Method for Life Path calculations: Month, Day, and Year are reduced independently down to single digits or Master Numbers (11, 22, 33) before being summed. This ensures structural preservation of Master Numbers according to 20th-century numerological convention.

Numerology is a symbolic framework for introspection. OmniZodiac makes zero deterministic destiny claims. All names and dates entered into our calculator remain 100% ephemeral in your local device memory.
