Modeling of Music Creation Process As an Application to Creative Arts Field of Yoshikawa's General Design Theory.

Abstract

General Disign Theory (GDT), which was presented by Yoshikawa in 1979, holds the possibilities 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. The purpose of this study is how the music creation process can be described by using GDT, and also researches the application possibilities to creative arts field of GDT. An expression requirement by a self-expression desire that was born from a composer's environment is generally symbolized on the form "music", and a performer interprets into the entity "sound" using above-mentioned music that indicates the attributes (pitch, dynamic and time value) of sound with the notation. In this paper, it deals with so-called "composition" which is the process form requirement to music. Generally, the creation processes of musical works in creative arts field are personal very much and most of the descriptions about process are ambiguous. By deducing various theorems about music creation process by using GDT, a clear description becomes possible. The gotten results don't have contradiction with musicology, and an application possibility to creative arts field of GDT is shown.
