	Art of Bamboo, The	箏 : Izumiyama Shoko 尺八 : 菅原久仁義
This duet for koto and shakuhachi was written by the leading koto composer and performer Tadao Sawai. The unique chacteristics of each instrument are developed through a dialogue between them. Both parts require the highest level of musical and technical ability. Particularly the fast passages require teamwork to produce the necessary tension and subtlety of expression. This is one of Sawai’s most important works.
