EXPLORATORY STUDY ON QUANTIFYING COMPLEXITY IN THE TEMPORAL STRUCTURE OF ELECTROACOUSTIC MUSIC

The music created by this study’s authors was electroacoustic, which is more complex than ordinary popular music. Individuals often consider highly complex music as being difficult to understand; however, this study’s social activities, in which individuals were encouraged to create their own electroacoustic music, indicated that all participants enjoyed it. This indicated that efforts in this social practice may be changing “difficult things” into “fun things.” This process of extending “fun things” is useful for extending the concept of “entertainment” in Game and Entertainment Technology. Therefore, this study aimed to verify that complexity in music increases in the order of “normal (8-beat, etc.) music, experimental popular music, electroacoustic music, and noise music.” To test this hypothesis, this study attempted to compare the rhythmic structure of “normal music” and “experimental popular music.” The results indicated that the rhythmic structure of the experimental popular music was more complex than that of normal popular music. Furthermore, it is strongly suggested that electroacoustic music, which has no rhythmic structure, has a more complex rhythmic structure. Furthermore, it can be stated that inexperienced individuals enjoyed the creation of “music” that has no clear rhythmic synchronization. This extended these individuals’ traditional concept of “entertainment”, and can be further extended by deepening this activity in the future.
