Gagok

Gagok is performed by male singers (namchang) and female singers (yeochang), either solo or in duets. Vocal lines are characterized by very long vowels, few syllables and a range limited to about two octaves. Songs are structured in multiple sections combining vocal and instrumental parts. The repertoire includes 41 compositions, collectively known as Mannyon changhwanjigo (“Song of Long-Lived Joy”), with 26 pieces for male voices and 15 for female ones. Pieces are performed in different modalities conveying varying emotions: pyeongjo (peaceful), ujo (energetic), and gyemyeonjo (melancholic).

Accompaniments and interludes are played by a small ensemble of traditional Korean musical instruments. The accompaniment features a small ensemble of traditional instruments: gayageum or geomungo (zithers), daegeum or sogeum (flutes), haegeum (two-stringed zither), piri (bamboo oboe), and janggu (double-headed drum). The balance between voice and instruments is a defining feature of the genre.

In the 20th century, a “Modern gagok” style emerged, influenced by Western music, particularly the German lied. During the Japanese colonial period (1910-1945), singing in Korean became a means of asserting national identity. one of the first modern pieces, “Bongseonhwa” (1920) by Hong Nan-pa, became a symbol of resistance. After liberation, the genre continued to evolve amid political and cultural tensions, maintaining a central role in Shaping Korean musical identity.
