Broken Bowls 4 - Talk
computer music based on an algorithmic instrumental composition

The composition is based on an algorithmic score for voice, clarinet, viola and piano. These instrumental sounds are then used to be electronically and digitally processed to a pieces of computer music.

The production of the electroacoustic composition has taken place at Sheffield University Sound Studio during a composers residency from July-August 1999 in SUSS Studio 2.

2     Der letzte Wassermann
 4 channel tape and live arco-piano

computer music based on an algorithmic instrumental composition distributed on 4 channel audio system will accompany  a prepeared piano, played live with string bows.

Chuang Se-Lien: arco-piano

arco-piano is a special contemporary technique of performing the piano with hairs of bows which gives a very sophisticated sound of the piano. Se-Lien Chuang developed arco-piano technique to the artistic point, where she can control polyphonic sound of the bowed piano strings and their upcoming overtones.

 realtime processing

Andreas Weixler: realtime audio processing
Chuang Se-Lien: Yan-Zin

The sound of an instrument will be processed live by the computer. The combination of natural and the transformed sound brings together traditional asian instrumental sound and contemporary western computer music by an improvisation of two musicians.

The max/msp patch has been programmed and rehearsed at the SUSS Studio1 at Sheffield University Sound Studio during a composers residence and has been finished at Atelier Avant Austria in Graz using Max 3.8.9/msp1 running on a G3 Macintosh computer.

 interactive audio visual performance for 2 instruments

artistic concept
based on the asian spirit of harmony the computer senses harmony between the players and voices and acts accordingly to them in generating audio and visual.

Waon is an audiovisual improvisation for two musical instruments.

In the first part voices of different nations (Taiwan, Japan, USA, Austria) will be analysed and transformed to melodies by oscillators and visuals by the computer.

In the second part, two live instruments are improvising from playing the same note, over micro tonal distortions up to free audiovisual improvisation. The computer senses the correspondence of the instruments and reacts in real time. If there is only one frequency, the system plays the same and everything is quiet and in tune (waon). If the notes are different from each other, the computer plays all notes inbetween as an electronic sound ambience. In case of very far distance the computer reacts with as much frequencies as possible, which could be a noise.
The analysis and reactions are displayed in real time by graphics, based on circles and their distortions, ovals.

Jade For Orchestra On Tape
 computer music

All sounds are created from natural instruments, male and female voices by digital transformation.

 Realization of Jade For Orchestra on Tape:

1. Calculation of the densities of the sound particles for the orchestra was done at AAA Atelier Avant Austria in Graz, 1994-1995. The instrumental and human sounds have been recorded in April 1995 performedby the austrian ensemble szene instrumental

2. Sound processing at the UEA Studio of the University of East Anglia, Norwich, England. in July August 1996. Algorithmic sound processing was controlled by an Opcode-Max patch developed by the composer.

3. The composition was done at the BEAST -Birmingham Electro Acoustic Sound Theatre, University of Birmingham, England in August 1996, Continuing the development of the controlling software HyperControl by the Composer.
