(The first version of the piece, made in November 2004, had a stereo soundtrack. In March 2005 I changed the video slightly and made a surround soundtrack.)

Program note

Dissonant Particles is an abstract animation.

Psychoacoustic experiments have indicated that when two pure sine tones are played simultaneously, they will sound most dissonant when they are around a semitone apart in pitch. In Dissonant Particles, each particle emits a sine tone. The dissonance between particles acts as a repulsive force which pushes them apart, both in position and in pitch. There is also a long-range (“cosmological”) attractive force that prevents the particles from flying off to infinity.

The particles pulsate and slowly evaporate; both of these processes affect the way they "feel" the forces acting on them. The colour of a particle indicates pitch: red for low pitches, green for intermediate, and blue for high. The camera tracks one particle, which is always shown in the centre of the screen.
