Dosei, Voices of the Earth

Dosei (土声), Voices of the Earth by Hikaru Sawai (1991)
Bass Koto and Shakuhachi

Dosei refers to the two voices born from the Earth. One is the resonance of the bass koto, the other the melody of the shakuhachi. The voice of the bass koto dances back and forth, while the voice of the shakuhachi sings of the life that is in the Earth. The two voices overlap, resonating together, and existing together.
