Aleksi Perälä, whose work for Rephlex and his own AP Musik has continuously sought to push electronic music’s boundaries, has created what might be his most extraordinary idea to date. Alongside Grant Wilson Claridge (who runs Rephlex) he has invented a custom musical scale called The Colundi Sequence, an alternative to the standard musical scales most music is composed from. Rather than dividing the keyboard into octaves with semitones, the pair chose specific frequencies to work with, making a scale of 128 resonant frequencies. These frequencies were selected through a variety of methods, including experimentation and taking from ideas on philosophy, psychology, science, human bio- resonance and mysticism. By pulling away from standard musical scales, Perälä has created some undeniably compelling music, filled with uncanny tones and precisely wrought sounds that are spellbinding in their unfamiliarity.

Colundi is a self-designed tuning system that uses only a certain set of frequencies—”128 resonant frequencies chosen via experimentation and philosophy, each relating to a specific human bio-resonance, or psychology, traditional mysticism or belief, physics, astronomy, math, chemistry,” to be exact,according to the label.

“What is colundi? we fail to reliably express our precise thoughts & intentions using words. consequently, you may fail to understand us. we apologise for the effects of such misunderstanding. common purpose. consideration of data. colundi everyOne.”
