![]() The method starts with generating an initial sequence of pitches with a musically informed module and then calculates the suitability of the pitch sequence through the embedded rules. Music theory is used for finding the suitability of its generated pieces. The key point with these four operators is that the uniform crossover operator and the first mutation operator are indiscriminate, in the sense of using no knowledge of music theory, whereas the employed one-point crossover operator and the second mutation operator are musically informed. Uniform and one-point crossover operators as well as two mutation operators conduct the search in the employed genetic algorithm. As an innovative feature, the procedure uses the combination of a genetic algorithm with a synergetic variable neighbourhood search. This paper presents a procedure which composes music pieces through handling four layers in music, namely pitches, rhythms, dynamics, and timber. ![]()
