about

This piece grew out of attempts to build a work based on the behavior of genes in biological systems. I've used a simplified model of sex and mutation: A string of bits defining a sound event (a "gene”) is randomly mutated–one bit, selected at random, is flipped–or the entire gene is cut in half and mixed with another one. These actions are all done under the control of keys on the computer keyboard, which either play events ("express" the gene), cause a mutation to happen, or cause an event to be "bred" with another. This set of controls defines an instrument, which I freely play in the performance: I fill the role of natural selection, by choosing to keep some sounds and discard others.
