김영길의 아쟁 - 박종선류 아쟁산조, 시나위 (Kim Youngkil's Ajaeng - Solo Recital for Ajaeng Sanjo in the Style of Park Jongseon, Sinawi)

Sanjo is a Korean instrumental solo genre characterized by a continuous suite of increasingly faster movements performed by a single melodic instrument with rhythmic accompaniment on the janggu (hourglass drum). It is best known through gayageum sanjo, but parallel traditions exist for geomungo, daegeum, haegeum, piri, and other instruments. The music unfolds through set rhythmic cycles (jangdan) that accelerate from very slow to very fast, while the soloist spins ornate, semi-improvised variations on core motifs. Typical modes (jo) include pyeongjo and gyemyeonjo, and the performance relies on signature ornaments (sigimsae) such as slides, microtonal bends, and vibrato. Sanjo is deeply expressive—moving from introspective pathos to exhilarating virtuosity—and is a cornerstone of modern Korean traditional performance practice.

Sinawi is a traditional Korean shamanic ensemble music characterized by collective, improvised heterophony over recurring cyclical rhythms (jangdan). Originating in late Joseon–era ritual contexts, it accompanies gut (shamanic rites) and dance, moving from slow, meditative sections to ecstatic, fast passages. Typical ensembles combine melodic instruments such as daegeum (bamboo transverse flute), piri (double-reed), haegeum (two-string fiddle), and gayageum/geomungo (zithers) with percussion like janggu (hourglass drum) and buk (barrel drum). Melodies draw on Korean modal systems (jo), especially gyemyeon-jo and ujo, with rich ornamentation, flexible intonation, and interlocking variations among players. Sinawi’s hallmark is spontaneous, conversational interplay: each performer elaborates the core tune while listening and responding to others, creating a living tapestry that can shift from solemn trance to vigorous release.

Korean folk music (minyo and related traditions) encompasses the vernacular songs, percussion ensembles, narrative epics, and ritual pieces that grew outside the court in villages and marketplaces across the Korean peninsula. It features cyclic rhythmic patterns (jangdan), pentatonic modal systems such as pyeongjo, ujo, and gyemyeonjo, and distinctive vocal ornamentation (sigimsae) that conveys the affect known as han (a bittersweet, often plaintive sentiment). Core idioms include minyo (regional folksongs like Arirang), pansori (long-form sung storytelling), sinawi (shamanic-rooted ensemble improvisation), and pungmul/nongak (outdoor farmers’ percussion), performed on instruments such as gayageum and geomungo (zithers), haegeum (spike fiddle), daegeum and piri (flutes/oboes), and the four samul percussion instruments (kkwaenggwari, jing, janggu, buk).
