Changjak gugak (창작국악, “creative national music”) is a modern compositional approach that creates new works using the instruments, modes, ornaments, and rhythmic cycles of Korean traditional music (gugak). Rather than simply reviving old repertoires, it extends them with contemporary forms, large-ensemble writing, and modern techniques. Typical instrumentation includes gayageum, geomungo, haegeum, daegeum, piri, ajaeng, various percussion (janggu, buk, jing, kkwaenggwari), and sometimes saenghwang and yanggeum. Composers often employ traditional modes (pyeongjo, gyemyeonjo), characteristic ornamentation (sigimsae/nonghyeon), and cyclic jangdan (e.g., jinyangjo, jungmori, jajinmori, gutgeori), while integrating ideas from modern and contemporary classical music. The result ranges from meditative chamber textures to full "gugak orchestra" works that explore heterophony, timbral color, and new formal designs, positioning changjak gugak as a bridge between heritage practice and present-day art music.
