Ryum was composed to create a close relationship between visual- and music based on Gagaku and Noh (traditional Japanese music) aesthetics. Both visual and music parts were composed in parallel so that musical and visual timing and speed of gestures and transformations can be delicately adjusted at any compositional and processing stages. This piece does not include any sudden explosions, surprising, or interruptions, as they are not the expression ways of gagaku. The subtle changes and slowly floating transformations and percussive sounds, which give from time to time accents to the floating phrases, are the manner of this piece.
The idea for visual part was inspired by Japanese textile industry Nishijin which has a long history of producing original style textile and has been in demand by the Gagaku and Noh performers for their clothes.
The title Ryu means stream and Mu means dream in Japanese.
