|In his writings from the 70s,
Nørgård interprets the three developed hierarchies (the infinity row, the golden rhythms
and the over and undertone harmonics) as an expression of the harmony of the universe. He
refers to the distances between the planets, their orbital periods, and the attempts that
have been made throughout the ages to link these phenomena with, for example, the
structure of the diatonic scale and the overtone row.
The infinity row is linked to creation myths and the weekly rhythm.
In the present context, however, further exploration of these ideas would be beyond the
scope of this material. It is a complicated subject, calling for knowledge of the
mysticism of numbers as well as of astrological and mythological ideas. Those who wish to
explore this subject further are referred to three articles in particular: Myter og
musik (Myths and Music), Er diatonik et universelt fænomen? (Is Diatonics a
Universal Phenomenon?), and Introduktion til hierarkisk genesis (Introduction to
Hierarchical Genesis) (all printed in Per Nørgård Artikler 1962-82).
