Teuroteu (or, somewhat derisively, ppongjjak) is the oldest form of Korean pop music, having developed in the years before and during the Japanese occupation. It has received criticism from nationalists, who allege that it derives from the Japanese music genre of enka. Defenders of Teuroteu refute this claim, citing development prior to Japanese invasion and parallel development as the reason for the similarities. The name itself, the Koreanised form of "trot", derives from a shortening of "foxtrot", a ballroom dance which influenced the characteristic simple beat of the genre. The genre has largely fallen out of favor in today's popular music scene.
