安東ウメ子・ムックリの世界《シリピリカ》アイヌ民族の心の響き (Shiripirika: Songs of Mukkur, Upopo and Tuitak)

Ainu music is the traditional music of the Ainu people of northern Japan (Hokkaidō) and the southern Russian Far East (Sakhalin and the Kuril Islands). It centers on communal singing, ritual chant, and dance songs tied to an animistic worldview in which spirits (kamuy) inhabit all things. Core vocal forms include upopo (short, often cyclical songs performed in groups), yukar (lengthy epic-chant narratives), and rimse/tapkar (dance songs). Instrumental timbres are distinctive: the tonkori (a long, five‑string zither) provides droning, ostinato patterns, while the mukkuri (jaw harp) creates pulsing, overtone-rich rhythms shaped by the mouth cavity. Textures are usually monophonic or heterophonic, with call‑and‑response, vocables, and handclaps or foot-stomps supplying rhythmic drive. Melodically, many songs favor pentatonic or modal frameworks and asymmetrical phrasing. Functionally, music accompanies ceremonies (such as the bear‑sending ritual, iomante), social gatherings, games, and lullabies, making it both sacred and everyday in character.
