Outline of Final Research Achievements |
We have been pursuing the formalization and construction of an algebraic system for a time-span tree provided by music theory GTTM as a typical example for representing intention. We have clarified the theoretical properties of a musical morphing algorithm, and proposed an approximating solution of a relative suedo complement using the flip operation newly introduced. As for musical applications employing tree structures, we have prototyped a composition system using melodic contour and a arrangement system reducing the voices included in polyphony. As for a musical analyizer, we have invented an new algorithm adopting a deep learning, and achieved a high precision rate of 80% to 90%. As for the deployment towards different media, we have proposed a discussion time-span tree and implemented an application system.
