WebernUhrWerk is a generative music generator Carillion (for Win XP or Mac X PPC or Mac X Intel)

Product Description:

A computer program that automatically composes dodecaphonic Carillon music based on the twelve-tone row of Anton Webern's last composition - commemorating his sudden and unexpected death on 15 Sep 1945 as he was accidentially shot dead by an American GI. The program simulates a Carillon which plays a short musical phrase every 15 minutes which never repeats itself.

Product Requirements:

    * Windows XP
    * Mac OS X 10.3 or later

This product is designed to run on the following operating systems:

    * Windows XP
    * Mac OS X 10.3.9
    * Mac OS X 10.4 PPC
    * Mac OS X 10.4 Intel

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, 4 independent rhythmical 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.
