This project aims to explore the sound of the multi string 17-string and 25-string koto. As well as works by contemporary composers, the recital program included two new duo pieces with the aim of creating a new vision for the 17-string and 25-string koto. Combining the views of composer Aki Mori and the performers, the new piece “Tsugaru　for 25-strings and 17-strings”communicated the world of writer Osamu Dazai underpinning the work, and took full advantage of the characteristics of the instruments. In addition, the familiar and delicate melody made it very easy to understand for audience members unfamiliar with traditional Japanese music, ensuring it was well received.
The revised 2023 edition of “Yume Koi Kaidan” composed by Yu Kuwabara was performed with natural vocalization in order to give a modern feel to the work, which incorporates vocals, narration, spoken lines, and chanting. While belonging to the genre of contemporary music, this work received especially high praise within the overall performance for its considerable entertainment value.
In addition, each solo covered the work of koto pioneers, displaying the individuality of both the performers and the instruments.
