Lexicon-Oracle

About...

This algorithmic text composition will reveal some of the infinite secrets of the realtime composition Lexikon-Sonate, pondering upon problems of algorithmic composition and post modern philosophy, in a never repeating, always mind-challenging way.

The text material was taken from several articles about Karlheinz Essl's Lexikon-Sonate (1992 ff.), an infinite interactive realtime composition for computer-controlled piano:

• Gerhard Eckel: About the Installation of Karlheinz Essl's "Lexikon-Sonate" at the Banff Centre for the Arts (Banff/Canada 1995)

• Karlheinz Essl: Lexikon-Sonate. An Interactive Realtime Composition for Computer-Controlled Piano (Canela/Brazil 1995)

• Karlheinz Essl: Composing in a Changing Society (Lecture: Ottawa/Canada 1995)

• Karlheinz Essl: New Aspects of Musical Material (Lecture: Darmstadt 1992)

These articles were processed by a multi-dimensional markov chain algorithm in order to achieve a "reading-through" of the different texts. By this a basic corpus of text particles was created which is stochastically re-combined by a CGI-script which was written by Florian Cramer.

Presentation of the Lexicon-Oracle within the Lexikon-Projekt

Originally, Lexicon-Oracle was conceived as a part of a multimedia installation at the Klangturm St. Pölten - the Lexikon-Projekt - where the electronic version of Andreas Okopenko's Lexikon-Roman was controlling the composition algorithms of Karlheinz Essl's Lexikon-Sonate for computer-controlled piano.
