A Dynamic Score System via Sound Visualisation

― A Tool for Sound Perception and Improvisation ―

Abstract

In the field of art and electroacoustic music the expansions of sound materials as well as a musical expression demand us an alternative approach to listen to music. Then, how shall we be able to acquire this novel aural perception and listening skills?

 

This paper introduces a dynamic score system On Gaku, having a discussion about the potential of a dynamic score as a tool for enhancing the ability of sound perception. On Gaku, which has been developed with sound visualisation technology, allows to notate real-time changes of sounds; on the other hand, the visualised graphics will be utilised as a music score by instrumentalists. Therefore, this score system introduces a sound-to-image-to-sound circulation and urges musicians to watch, play and listen to sounds simultaneously. As a result, practicing with the system could be thought to improve musicians' novel sound-base listening skills. In this paper the efficiency of the system is also inspected, adducing two cases of music performances with the comparison of musical expression.
