Constants

Basis Changes

These Map2D constants are available to change to and from:

• The Wicki-Hayden coordinate system of (M2, P5) vs. Meantonal’s (M2, m2).
• The “generators” map of (P5, P8), which is useful for mapping arbitrary note names to frequencies in non-EDO meantone tuning systems like quarter-comma or golden meantone, which have an infinite number of pitches and are generated by their octave and fifth.

const WICKI_TO = new Map2D(1, -3, 0, 1);
const WICKI_FROM = new Map2D(1, 3, 0, 1);
const GENERATORS_TO = new Map2D(2, -5, -1, 3);
const GENERATORS_FROM = new Map2D(3, 5, 1, 2);
