about

Born in Vienna, 15 Aug 1960. Austrian composer, performer, improviser, media artist and composition teacher.

Karlheinz Essl attended the Vienna Musikhochschule (1981-87), where he studied composition with Friedrich Cerha and electro-acoustic music with Dieter Kaufmann. From 1979, he also studied musicology and art history at the University of Vienna (doctorate 1989 with his thesis Das Synthese-Denken bei Anton Webern). Active as a double bassist until 1984, he played in chamber and experimental jazz ensembles. As a composer he has contributed to the Projekt 3 composition programming environment of Gottfried Michael Koenig at Utrecht and Arnheim (1988-89) which later transformed into his own Real Time Composition Library (RTC-lib) for Max/MSP/Jitter.

Essl also served as composer-in-residence at the Darmstadt summer courses (1990-94) and at IRCAM (Paris, 1992-1993). Between 1995-2006 he taught Algorithmic Composition at the Studio for Advanced Music & Media Technology at the Bruckner University, Linz. Since 2007, he is professor of composition for electro-acoustic and experimental music at the Vienna University of Music and Performing Arts. Between 1992 and 2016, he acted as the music curator of the Essl Museum in Klosterneuburg / Vienna.

His work with computers (with emphasis on Algorithmic Composition and generative art) and a prolonged occupation with the poetics of serial music have been a formative influence on his compositional thinking. He has frequently sought to combine music with other genres and has collaborated with the graffiti artist Harald Naegeli (Partikel-Bewegungen, 1991), the writer Andreas Okopenko and the artists' group "Libraries of the Mind" (Lexikon-Sonate, 1992--8), the architect Carmen Wiederin (Klanglabyrinth, 1992-95), the video artist Vibeke Sorensen (MindShipMind, 1996, a multimedia installation for the Internet) and the artist Jonathan Meese (generative video and sound environment FRÄULEIN ATLANTIS, 2007).

During the 1990s Karlheinz Essl carried out various projects for the Internet and became increasingly involved with improvisation. At the festival WIEN MODERN 1989 he presented as an emerging composer, and in 1997 he was featured at the Salzburg Festival with portrait concerts and sound installations. In 2003, he was artist-in-residence of the festival musik aktuell, and in 2004 he was presented with a series of portrait concerts at the Brucknerhaus Linz. In 2004, Karlheinz Essl received the cultural prize for music of the state Lower Austria.

Besides writing instrumental music, Karlheinz Essl also works in the field of electronic music, interactive realtime compositions and sound installations. He develops software environments for algorithmic composition and acts as a performer and improviser, utilzing his own computer-based real time composition environment m@ze°2 and also instruments like electric guitar, toy piano and music box.

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!
