The Art of the Koto, Volume 3: Works for Nijūgen

Folk is a song-centered acoustic tradition rooted in community storytelling, everyday life, and social history. It emphasizes clear melodies, simple harmonies, and lyrics that foreground narrative, protest, and personal testimony. As a modern recorded genre, folk coalesced in the early-to-mid 20th century in the United States out of older ballad, work song, and rural dance traditions. It typically features acoustic instruments (guitar, banjo, fiddle, mandolin, harmonica), strophic song forms, and participatory singing (choruses, call-and-response).

Sōkyoku (箏曲) is the classical Japanese repertoire for the koto zither that gained prominence in the Edo period. Centered on the 13‑string koto, it features refined timbres, flowing melodies, and an emphasis on space (ma) and expressive nuance. Although performed primarily on the Japanese koto, the idiom is closely related to the broader East Asian zither tradition; in some modern or cross‑cultural contexts, the Chinese guzheng may be used to render sōkyoku repertoire. Sōkyoku is often heard solo or within the sankyoku ensemble alongside shamisen and/or shakuhachi, creating an intimate chamber texture. Core forms include danmono (theme‑and‑variations instrumentals) and kumiuta (song cycles), and the music frequently employs traditional koto tunings such as hira‑jōshi and kumoi‑jōshi. The performance aesthetic values subtle ornamentation, flexible rhythm, and lyrical expression.
