Human-Machine Musical Composition in Real-Time Based on Emotions Through a Fuzzy Logic Approach

This work proposes a method for representing human emotions, in the context of musical composition, which then will be used to artificially generate musical melodies through Fuzzy Logic. A real-time prototype system, for Human-Machine Musical Compositions, was also implemented to test this approach, using the emotional intentions captured from a human musician and later used to artificially compose and perform melodies accompanying a human artist while playing the chords. The proposed method was tested with listeners in an experiment with the purpose of verifying if the musical pieces, artificially created, produced emotions in them and if those emotions matched with the emotional intentions captured from the human composer.
