Sankyoku is a refined Japanese chamber music tradition centered on an intimate trio of instruments—koto (13‑string zither), shamisen (three‑string lute), and originally kokyū (bowed lute). From the late Edo period onward, the kokyū part was increasingly performed on shakuhachi (end‑blown bamboo flute), which is now the most common third voice. The ensemble frequently supports a vocalist, with all parts weaving a delicate, ornamented heterophony around a shared melody. The repertoire draws on jiuta/sōkyoku song types and instrumental forms such as kumiuta, danmono, and tegoto‑mono, featuring characteristic tunings (koto: hira‑jōshi, kumoi‑jōshi; shamisen: honchōshi, niagari, sansagari) and the expressive pitch inflections of shakuhachi (meri/kari, yuri). Texture, pacing, and phrasing foreground ma (silence/space) and the overarching aesthetic arc of jo‑ha‑kyū (introduction–development–rush), yielding music that feels poised, introspective, and conversational.
