Music By: Karlheinz Essl
Mixed Mastered cureated and Artworked by: Tiago Morais Morgado

This generative drone scape is based on a sequence of 25 chords which have been recorded by Karlheinz Essl on a Shrutibox - an instrument which used in traditional Indian music for creating long drones. The sound is produced by slowly moving a bellow which creates an airflow that is directed towards a series of pipes fitted with reeds. These pipes can be opened or closed with adjustable buttons. By this, a large variety of chords can be created out of 13 chromatic pitches within a single octave.

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:

1 2
1 2 3 2
1 2 3 4 3 2
1 2 3 4 5 4 3 2
....
The entire process lasts 12 hours before the whole hypercycle will be starting again.

The piece was created by computer program written in Max, using compositional algorithms from my 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!
