Abbys belongs to a series of pieces I have written for solo performer and electronics. Like in the previous pieces of this series (Elpia II, STRINGendo, Flautando), the playing of the performer is transformed into MIDI data. The MIDI data is processed on four independent layers by a computer program I've written which then control a sampler, playing all sorts of sounds and noises previously recorded from the particular instrument. Pitches and velocity values can be transformed, notes can be delayed, a played note can trigger many other notes etc. Each of the processing parameters can either be exactly determined, or it can be defined as a random interval within which the processing will be carried out. The live performance keeps the piece fresh while the fact that processing is done on four separate layers enables the performer to trigger complex musical textures. Furthermore, tape parts are played back in some sections of the piece. |
