Modulation in the sense of music theory: transition from one harmonic state to another
- here a process automated by computer algorithms. Central chords are paraphrased
by single voices that are determined by search algorithms according to statistically
defined differences to these chords. Rhythms are more strictly defined -
four instrumental layers (roughly: wood, brass, piano and mallets, strings)
are parts of rhythmical patterns that change slowly over different sections.
Also: modulation as a variation of the method modulation and an echo of tonal music.
Instrumentation: 1(picc)/1/1, asax/1 - 1/1/1/0 - mar - vib - pno - 2/1/1/1
