Teuroteu (트로트) music is a combination of fox trot music, jazz and traditional Korean music. Teuroteu music became popular after WWII, when American musical influences were inspiring Korean artists. Teuroteu is especially popular with older audiences, but it’s making a slow comeback with younger audiences.

You may have heard of Tae Jin Ah (태진아) through his son, Eru (이루), who is also a singer. He has a nice, husky voice, which can be heard in 짝사랑 or “Unrequited Love”
