Certain Fluctuations was written as an exercise in process-based composition. I started with a chord (C, F, G, and D) and then constructed a set of rules (through much trial and error) for each of the four voices of that chord to follow. I then let the "program" run. If there were any moments along the way that didn't feel right to me, I'd modify a rule and run the program again until I was satisfied. The result is a meditative, serene sonic experience.
