WebernUhrWerk

Generative Music Generator in Memory of Anton Webern
© 2005-2015 by Karlheinz Essl


Apple Software   vs. 3.0     NEW
released: 20 Jul 2015

With authentic bell sounds from the Belfry Carillon (Ghent, Belgium)!



Like all of Karlheinz's shareware, this is extraordinary. Weird interface, strange nomenclature and completely original. On the web radio station I will someday open (www.robotradio.net) this music and the other Essl soundscapes will be the signature sound. Don't put radio on computers -- put the computers on the radio!

For Whom the Bell Tolls

On September 15th, 1945 the Austrian composer Anton Webern was accidentially shot dead by an American GI in Mittersill, Salzburg where Webern had escaped from the Russian invasion.

WebernUhrWerk (translated: Webern's Clockwork) was composed as an open-air sound installation for the 60th anniversary of Webern's death which took place on 15 September 2005 on the market place at Mittersill. A loudspeaker placed into the open roof window of the city hall was connected to the audio output of this program. Every quarter of an hour, a short musical phrase with a Carillon sound was played which could be heard all over the city - like the sounds of bells ringing every 15 minutes.

This action will be continued every year on September 15th. If you want to share the memory of Webern with us, you can join us by starting the WebernUhrWerk program and play its sound output over a loudspeaker system - at home, during a public event or even in open space.

Compositional Aspects

This realtime composition is based on the twelve-tone row of Anton Webern's last opus which he started in Mittersill and which he was unable to finish due to his unexpected death:


Twelve-tone row of Anton Webern's unfinished op. 32


This series serves as the basic material for a composition algorithm that generates music in real time which never repeats itself. The row is subjected to an algorithm that uses the structure of the series as its own permutation program. The pitch classes are then mapped onto fixed registers of which 6 different models are existing - minor seconds, major seconds, minor thirds, major thirds, a combination of minor and major seconds and finally a sort of all-interval row. Each model is represented by a twelve-tone chord where each pitch class occurs in a fixed register.

For each quarter of an hour, four individual compositional models have been created. Although their outlines are defined, infinite variants are obtained by utilizing random procedures and aleatoric methods for constructing the rhythmic structure.


Programming Aspects

WebernUhrWerk is written in MaxMSP using my Real Time Composition Library (RTC-lib), a collection of compositional algorithms and tools which I have been developing since 1992. The programming structure of "WebernUhrWerk" is completely transparent - if you double-click one of the grey boxes, its hidden content would show in a new window. If you are experienced in Max or Pd you can easily understand how the program function.

REplay PLAYer is a computer program that de-constructs a given sound file and re-composes it by using realtime composition algorithms. It can be used as a tool to generate an infinite and every-changing sonic stream from a single sound file for artistic, compositional or mere recreational purposes. It can also be regarded as a computer based instrument for live performances, as an interactive sound installation or a generator for ambient music.
