Darwinian Pianos: Realtime Composition Based on Competitive Evolutionary Process
In this project a composition is achieved by two separate evolutionary algorithms (virtual pianists) executing and modifying a repetitive phrase in a cooperative manner - conversely this collaboration is directly counteracted by deliberate placement of a tone within the repetitive phrasing by one or other of the pianists. This action creates conflict and consequently it becomes a challenging task for the opposing pianist to introduce a similar change - thus the effect becomes combative and may be witnessed by an audience. The genetic representation for pitches is based on prime-number ratios and assigns lower Hamilton distances to more harmonically related frequency pairs. This and a special way to evaluate musical structure based on it seems to be correlated with good results in generated music pieces. Finally possibilities are discussed to bring “Darwinian Pianos” into musical practice.
