### Defining Moments of Symmetry

An infinity of new scale families are shown via Marcus Hobbs’ animation of moving generators along Wilson’s Moments of Symmetry continuum. Generators are an initial condition for a note generating formula.

Kraig Grady’s Wilson Archives has a simple “cliff notes” definition of a Moment of Symmetry. A Moment of Symmetry is a scale that consists of:

- A Generator (of any size, for example a 3/2 or a fifth in 12 equal temperament).
- An Interval of Equivalence (of any size, for example most commonly an octave)
- A Scale Degree or Scale Unit represented by no more than two sizes only (Large = L and small = s)

The Generator is repeatedly superimposed but reduced within the Interval of Equivalence with only the large and small Scale Degrees or Scale Units.
