sankyoku

Sankyoku is a genre of Japanese chamber music that typically features three instruments: the koto (a 13-stringed zither), the shamisen (a three-stringed lute), and the shakuhachi (an end-blown flute). The term "sankyoku" literally means "music for three".12

The sound ideal in much of Japanese traditional music, including sankyoku, is to achieve a maximum effect with a minimum of material. This often involves a focus on the distinct timbre of each instrument, allowing each to be heard clearly, rather than blending them into a single sound as in Western orchestral music.1

The koto has a long history in Japan, appearing in the court during the 8th century. Over time, schools like Ikuta and Yamada developed, contributing to both solo and chamber music repertoires. The shakuhachi, a variant of the Chinese xiao, also developed distinct schools and repertoires, with its sound often described as introspective and reminiscent of Buddhist chant.324
