Gliding is an algorithmic piece generated in Mathematica, Wolfram Research Inc., by the 3-color Cellular Automaton 6148201356997. The evolutionary property of this CA is a uniform, repetitive background with discrete streams of irregular cell distribution, called gliders. The random initial conditions, 100 cells wide, generate gliders which increase and decrease in an unpredictable way until they eventually settle, forming cyclic behavior; repetition of a simple pattern. The electronic section comes from two simultaneous processes of settling which generate the form of the piece, as well as pitch, rhythm and register placement. The percussion part is based on improvisation, giving reference points in time and forming metric grouping. The only sustained sound in the piece, produced by a scratched cymbal, creates an additional layer, hovering over the structure of the piece as a kind of an echo of a hidden melody.
