Further Adventures of the Sonomorphs

چکیده
In 1993, I reported the results of preliminary work on the application of genetic algorithms (GA's) to music.1 This research was inspired by Oxford zoologist, Richard Dawkins2 who describes his journeys through a genetic cyberspace where he models the evolution or organisms he calls "biomorphs." Each biomorph is a small graphic image drawn by a recursive subdivision algorithm that is driven by a numeric vector. Dawkins likens this vector to a genetic code. In each new generation, biomorphs are bred by causing small random mutations in the vector. A series of children are born from which he selects the parent of the next generation based on subjective visual criteria. His thesis is that complicated organisms are not the result of chance or conscious striving toward a long term goal. Rather, they arise from the accumulation of small changes that assure the survival of the fittest. The process immediately reminded me of the means that composers use to search the space of musical constructs to find just the right choice for a particular moment in a piece.

متن کاملFemale Persian Scholars' Resistance to "The Orientalist Construction of Persia": A Critique of James Morier's The Adventure of Hajji Baba of Ispahan
The Western fascination with Persia, intensified though it was by the nineteenth century obsession with Indo-European languages, extends back into the classical origins of European culture. As Edward Said notes, Aeschylus' The Persians demonstrates how deeply embedded in the European mind is the belief in Persia's quintessential status as an Oriental society. For many Orientalists Persia demons...
