Korean ballad (often called K-ballad) is a slow- to mid-tempo strand of Korean popular music centered on emotive vocals, lush melodies, and dramatic climaxes. It typically features piano- or acoustic-guitar-led accompaniment, orchestral strings, and polished pop production, with lyrics that dwell on love, longing, parting, and memory. Musically, it blends Western pop ballad and soft rock harmony with R&B phrasing, frequent key changes for the final chorus, and expressive techniques such as melisma, vibrato, and dynamic swells. Since the 1990s, the style has also been tightly associated with K-drama OSTs, where its sentimental pull and cinematic arrangements reached wide audiences across Asia and beyond.

Trot (teuroteu) is one of the oldest forms of Korean popular music, built around a steady two-beat groove, simple diatonic harmonies, and highly ornamented, vibrato-rich vocals. Its melodies often use pentatonic contours and a characteristic catch in the voice (kkeokk-gi), conveying both festive spirit and deep pathos. Emerging during the early 20th century, trot absorbed influences from Japanese popular song (enka/ryūkōka), Western ballroom dance rhythms (such as waltz and tango), and Korean folk vocal aesthetics. The genre centers lyrical themes of love, longing, nostalgia for hometown, and everyday resilience, and it continues to evolve through modern “semi-trot” and television-driven revivals.
