Modeling of Music Creation Process As an Application to Creative Arts Field of Yoshikawa's General Design Theory (2nd Report, Requirement Space and Mental Space)

Abstract

General Design Theory (GDT), which was presented by Yoshikawa in 1979, holds the possibility that the object can be also applied to creative arts field in addition to narrow sense artifacts, because the description of GDT is very wealthy in abstract-ability and generality. In the 2nd report, as the extension of GDT, it added Requirement Concept Set to GDT and it modeled in Requirement Space. A Set of the worlds where the concepts produce the possibility to be formed in referring without experiencing entities is named the referable world. By introducing the referable world's Entity Concept Set, a modeling of Requirement Space became possible. Mapping from Requirement Space to Sound Image Space which is formed from the referable world's Entity Concept Set is possible to be also described by Modal Logic. The description of the relation between Entity Concept Set and referable world's Entity Concept Set has the possibility that Mental Space theory can be applied, and referred to the application possibility of Channel Theory to formalize the input and output of a connector in Mental Space.
