Outline of Final Research Achievements

We developed two systems based on a) symmetrical human cognitive biases and b) control of the amount of information entropy for the quantitative treatment of musical emotion. The former system was designed by the application of the loosely symmetrical biases model to the pitch element in existing melodies by regarding musical expectations as causal relationships; its inference is formed by preceding and succeeding events. The latter system was designed by controlling the degrees of certainty of musical events based on the information entropy to generate the musical structures. We presented these achievements at international conferences and to Japanese societies. Additionally, we presented successively applied knowledge and models as steps of this research practically to the composition of electroacoustic music pieces presented at worldwide concerts.
