いぶき (Ibuki)

World music is a broad, industry-coined umbrella for traditional, folk, and contemporary popular styles from around the globe that fall outside the Anglo-American pop mainstream. The label emerged in the 1980s as a retail and marketing category to group diverse regional musics for international distribution. Musically, it spans acoustic and electric instrumentation; modal, pentatonic, and microtonal pitch systems; and rhythms ranging from cyclical grooves and polyrhythms to asymmetrical meters. While the term can obscure local specificity, it also facilitated cross-cultural collaboration, festivals, and recordings that brought regional genres to wider audiences.

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).

Country is a roots-based popular music from the rural American South that blends Anglo-Celtic ballad traditions with African American blues, gospel, and string-band dance music. It is characterized by narrative songwriting, plainspoken vocals with regional twang, and a palette of acoustic and electric instruments such as acoustic guitar, fiddle, banjo, pedal steel, and telecaster guitar. Rhythmically it favors two-step feels, train beats, shuffles, and waltzes, while harmony is largely diatonic (I–IV–V) with occasional country chromaticism and secondary dominants. Across a century, country has evolved through substyles like honky-tonk, the Nashville and Bakersfield sounds, outlaw country, neotraditionalist revivals, pop-country, and country-rap hybrids, but it consistently prioritizes storytelling about everyday life, love, work, faith, place, and identity.

Japanese folk music (min'yō and related regional traditions) is the collective body of vernacular song and instrumental practices that arose among Japan’s rural and coastal communities. It includes work songs (rice-planting, fishing, sake-brewing), festival and dance songs (Bon-odori), travelers’ and boatmen’s songs, lullabies, and ritual/seasonal chants. Melodies commonly draw on pentatonic collections such as the yo and in scales, and are richly ornamented with kobushi (vocal turns) and flexible timing shaped by ma (intentional silence/space). Textures are largely monophonic or heterophonic, with unison singing doubled by instruments like shamisen, fue (transverse bamboo flutes), shakuhachi, and sometimes koto; taiko and local percussion support dance and procession contexts. Regional styles (e.g., Tsugaru in the north, Amami in the south, Okinawa and Ainu traditions) contribute distinctive timbres, rhythms, and repertories that together define the breadth of Japanese folk expression.
