Genetic algorithm to generate music compositions: A case study with tabla

Abstract

The paper proposes a methodology to create valid music compositions using genetic algorithm. Indian percussion instrument tabla is used as a prototype for this purpose. For any given taal, the methodology could generate new compositions from randomly generated initial population of standard bols of the tabla. A unique alpha-numeric representation is used for string representation. Typical genetic operators like selection, crossover and mutation have been used, but with tailor made modifications to incorporate unique features of the instrument under study. Fitness function incorporates the concept of fuzzy string matching. Experiments were conducted using different taals and different population sizes. The computer-generated compositions have been validated by human experts for its validity and novelty.
