OVALLE CUERVO, Clara Marcela; RAMIREZ CORREDOR, Sebastián  and  ESPITIA CUCHANGO, Helbert Eduardo. SYSTEM OF POLYPHONIC ARRANGEMENTS GENERATION FOR TRADITIONAL MUSIC OF THE COLOMBIAN ANDEAN REGION BASED ON GENETIC ALGORITHMS. Cienc. Ing. Neogranad. [online]. 2018, vol.28, n.2, pp.83-103.

In this paper, genetic algorithms are applied to the creation of polyphonic arrangements for traditional music from the Andean region in Colombia. This application is considered a type of evolutionary art, being codification and the target function used in the genetic algorithm of utmost importance to obtain the expected result. Our main contribution is to propose the codification of musical notes based on length and pitch, and the use of musical harmony rules. The system performance is analyzed from mathematical and musical standpoints.

Keywords : codification; Colombian Andean music; genetic algorithm; musical arrangements; polyphony.
