Tim Kreger: Babel's Legacy

Abstract

"This piece uses a DNA based algorithm to generate and manipulate melodic data. The entire piece has been generated from the melodic 'seed' which opens it. The algorithm iteratively produces variations on the melodic material present in the system at the time of generation. There are periods of growth in material as well as periods of decay, where melodic information becomes scarce. The rising and falling drone-like patterns in the background are also produced using a variation on this method. The spatial location and movement of the melodic parts are controlled by a non-linear equation known as a Lorenz Attractor. The piece deals with the constant evolution of information systems. Although the language of the piece continues to change, at any point one can hear its entire history of evolution. The reference to Babel in the title ties together the ideasoi DNA and 'the mother tongue', and this is perhaps the most important concept within the piece." -- Tim Kreger
