The sequence of 25 chords played on a chromatic Shrutibox

The piece starts with the note F, and slowly moves towards the dyad F-C, the perfect fifth which is often used in classical Indian music. The next chords is D-F-C, followed by the four-part sound D-F-G-C. In the fifth chord, the diatonic system is broken by replacing the D by C#. From there on, all chromatic notes are used until chord #12.
In the transitions from one chord to another, only one pitch changes which results in a very slow harmonic transformation. However, the progression does not simply move in one direction. Instead, a helix-like process is introduced that always goes back to the origin (sound #1, the F) before it reaches a new chord:
The entire process lasts 12 hours before the whole hypercycle will be starting again. This release, however, only contains the first part with a duration of approx. 3 hours.
The piece was created by computer program written in Max, using compositional algorithms from Karlheinz Essl's Real Time Composition Library (RTC-lib, a open-source software library for Max). Time stretching, tiny pitch deviations and the careful use of flanger and reverb create a everchanging drone scape with a surprisingly rich inner life, ideal for deep listening, meditation, and relaxation. It's cosmic music without being esoteric!
