Koncepcja generowania utworu muzycznego przez maszynę – akt sztucznej twórczości opartej na algorytmach genetycznych

The paper presents the examples of melodic line generated in a completely automated way, without human participation, using genetic algorithms, authors’ concepts and implementations. Fitness functions used in the algorithm consider several perceptual aspects of esthetical evaluation of musical creations. Hence the following do not occur in the generated individuals-compositions: dissonance, excessive frequency range, excessive tonal volatility. The artistic value of compositions was not assessed, since this could be accomplished only through statistical listeners’ polling, nevertheless the compositions do not irritate, staying in compliance with human esthetical paradigm.
