Infinity series
From Wikipedia, the free encyclopedia
The infinity series (Danish Uendelighedsrækken) is a method discovered by the Danish composer Per Nørgård for serializing melody, harmony, and rhythm in musical composition. The method takes its name from the endlessly self-similar nature of the resulting musical material, comparable to fractal geometry.
Nørgård discovered the melodic infinity series in 1959 and it proved an inspiration for many of his works during the 1960s. However, it was not until his Voyage into the Golden Screen for small ensemble (1968) and Symphony No. 2 (1970) that it provided the structure for an entire work. The harmonic and rhythmic infinity series were developed in the early 1970s and the three series were first integrated in Nørgård's Symphony No. 3.
