ABSTRACT
This paper presents a model of discrete musical composition based on musical writing techniques proposed by Johann Sebastian Bach. The model was implemented using the Meta-heuristics strategy, namely using Genetic algorithms implemented on the JGap Framework, producing musical results with a syntax that matches writing and music composition techniques. This approach is applied to the natural musical scale, and also to synthesized sounds of the natural-piano octave. Chords were created by taking the corresponding grades in the scale; additionally, notes and chords were grouped to become actual score bars.Using the proposed model, the following is obtained: 1) A set of notes grouped in bars with their corresponding interpretation, following the guidelines of syntactic JFugue Framework; 2) the score of the fragments produced written on a stave that complies with the rules of formal notation. Three MIDI files corresponding to three compositions (made by the computer) are presented, showing a strong evolution of sound and, as such, an audible result of a song.
