Eratosthenes' Sieve gets its title from the Greek philosopher Eratosthenes, who devised a 'seive' by which he could judge a number to be a prime number. I attempt to reflect this way of working in my formal approach to this work, by continuously evaluating and responding to new material inside existing material, a continuous 'sieving' of material. This creates a structure which continuously re-evaluates itself, and disperses both with, and against, the flow of 'musical' time, and in which the musical 'DNA' is reflected at both the micro and macro level, like a self replicating feedback loop, or fugue, it avoids the teleological yet remains goal orientated.
