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 PPC
    *Mac OS X 10.6 or later Intel

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 ~ 10.9 (+?) 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.

 For those having troubles to run the my computer program „WebernUhrWerk”, I have created a really long recording that you can use on any computer. Just start it at the beginning of a full hour and let it run. When finished, you can repeat the piece as long as you like. Be aware that  the piece consists mostly of silence! You will hear a short Carillon phrase exactly every 15 minutes - just like a church bell. If you wish, you can also download the file in order to play it from your mobile device.

  5 hour recording of WebernUhrWerk

 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
 12-tone row of 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.
