1. ”Projection Esemplastic” (1964) – sound file
When I was asked to create electronic music for NHK, I decided to use only white noise, which originally contained all frequencies, and cut out various components from it to compose the sound, instead of the idea of Western electronic music, in which electronic sounds are piled up to compose music.

2. “Icon” on The Source of White Noise” (1967)
Also uses white noise as a material, but it was developed from the previous piece and a multi-channel system was adopted. In the original version, several sound images of different widths (e.g. three loudspeakers playing simultaneously) move at different speeds around the listener, who is positioned inside the pentagonal loudspeakers.

3. ”Voices Coming” (1969) – sound file
When I thought about what exactly defines a human being, I felt that the production of music and the production of the human voice are both present at the same time. There is also the production of speech, which defines the self and the other. Human communication consists of a trilogy of languages.

4. ”My Blue Sky” (1976)
While many works of electronic music had already been created and various techniques had been used, I created this work because I thought I could still create a new form of expression. The work pursues expressiveness through the use of beat sounds obtained by periodically shifting sine waves through a gate and varying the gate period, gate width, frequency of the original sine wave, and other factors.

Bonus Tracks:

5. “Opening Bell at NHK Hall” (1973)

6. “Music for the Main Pavillion of the Okinawa Oceanic Expo” (1975)
This composition, music concrete work was made prepared for the Oceanic Expo in Okinawa prefecture in 1975. Folk music with an indigenous string instrument (Jamisen), voices of various sea birds, engine sound of a boat, metamorphosed instrumental sound which would remind wind and waves of the sea and chamber orchestral music are combined and constructed. An Italian Folk Song is arranged for chamber orchestra and recorded by the composer as important sound source of this music concrete work, which should be listened as if a recurrent, dear old tune being swayed on the wind coming out of one's rememberance. - from liner note of Edition OP
