Etude pour usines à fer (1996)
Homage to Pierre Schaeffer
Instrumentation: for electronic tape
In this ‘etude’ it was my intention to tease out elusive yet perceivable rhythms from short sound recordings taken in a steel foundry. I worked primarily with a computer programme, actually intended for use in the restoration of old LP recordings, whose undesired side effects interested me.

Krebsgänge (1997)
for René Krebs
Instrumentation: for jazz musician (see snails, trumpet) and an interactive computer system
A dialogue between an improvising musician and two computer programmes whose reaction to the musician’s performance is partly predictable and partly unexpected. The movements of the musician are registered using a video camera and then used to control a recording and play-back apparatus. The sound material for this piece is extracted from the musician and is continuously transposed and transformed by the computer.
The predetermined musical structure is suggested to the improvisor by way of the computer’s reactions - s/he has the possibility, however, to override them.

Brouillard - débrouillé 2 (1999)
for Matthias Müller
Instrumentation: for bass clarinet and an interactive computer system
The beginning of this piece finds the player in the midst of an extremely dense ‘Brouillard’, a fog. Cautious groping or, depending on temperament, courageous interposition allows the player to explore their immediate environment. S/he is gradually ‘débrouillised’ and acquires a certain confidence in the handling of this environment. Diverse sound processes are provided by the background score hidden in the computer.

Bruno Spoerri: (2002)
for Barb Wagner & Werner Bärtschi
Instrumentation: for two pianists and an interactive computer system
This piece consists of 15 periods, each with a duration of 48 seconds. The process of sound production follows a score ‘hidden’ in the computer, which, as with the score of the interpreters, is derived from the intervals of a twelve-tone series. The contrast between the incessant sequence of the computer controlled sound and the extensively defined yet inevitable variability in timing and detail in the action of the interpreters allows each performance to result in a new version of the piece.

Verklungen (2003)
Instrumentation: for electronic tape
The sound of my mothers violin has not been heard for a few years now: she died in 2000. During the course of her varied life her violin career repeatedly stagnated; in the last years of her life the afflictions of old age silenced her completely. I attempt to capture my memories of her in this piece.
The composition tells her story in a manner similar to that of the jazz improvisor doing a soli.
Associations, stray thoughts and suddenly increasing anxieties play an integral part.
