Beautiful Carin Levine commissioned this piece for her CD The Flute Experience. This is an excerpt. The Electronic Instrument uses feedbacks through a piece of Wood and a Bass Pump transducer with additional Guitar distortion. I am improvising this live together with the written part of the flute.

Ensemble Modern playing. Tape is a timestretch of the spoken work Harmony. A sort of canon between the tape and the players.

Clones is a one hour piece for two high sopranos, two percussionists, double-bass clarinet and live electronics. The electronic sounds are made with csound, max/msp and a custom-build sound spatialisation system using 8 speakers in a rectangular prism.

Clones - Excerpt

The final section of 'Clones'. The two high sopranos, percussion , double-bass clarinet and live electronics are now extended by a natural thunderstorm approaching the concert venue.

'Ad Infinitum' is a tribute to Jean-Claude Risset, composer and pioneer of Computer Music, who passed away in November 2016. One of his many contributions (together with Roger Shepard) was an acoustic illusion, the famous infinite glissando. My composition explores his glissando in a polyphonic way by using various transformations. First, the speed of the glissando is continuously changed. Secondly, the harmonic series is used to transpose the glissando and to transform its sound via granular synthesis. Finally, several voices are composed together and projected in circular movements around the auditorium.
The piece uses an implementation of Risset's glissando in csound. The usual sinusoids were replaced by square–waves. The classic algorithm is further modified to have a precise control over the tempo and the direction of the glissando in real–time. Several versions were recorded with interaction in real–time. The resulting sounds were further processed by granular synthesis modules in Cecilia (csound and pyo version). The spatialization of the piece uses 3rd order ambisonics, which was generated with csound. Furthermore, a trigonometric formula is used for the accelerandi and decelerandi of two pulse streams towards the end of the piece that signify a translation of Risset's pitch–based glissando to a 'glissando' in the rhythmic domain.

This is a piece for solo piano (and a little bit of electronic sound) I wrote after staying at the Birken Buddhist Monastery in British Columbia. The Monastery is surrounded by an ancient grove of Aspen trees. The beautiful photo was taken by Dave Getzschman.
