koreanlit1-4, Exercise 2: The history of gasa

Model answer:

The article divides the history at the Japanese invasion of 1592 to 1597. Before: themes of female beauty, war and seclusion, mostly yangban writers. After: moral instruction, travel, banishment and personal misfortunes, mostly commoner writers.

Three problems with the article: (1) it describes the form as paired four-syllable units but elsewhere says the first unit has "three or four syllables"; (2) "Only twelve gasa pieces survive to this day" has no citation; (3) it is silent on women authors (it says gasa were popular among yangban women, names Hwanggyesa as about a woman's longing, and names no woman as an author). Also: "it is unclear as to how they were sung", and two references point to the same Britannica link.
