Rock is a broad family of popular music centered on amplified instruments, a strong backbeat, and song forms that foreground riffs, choruses, and anthemic hooks. Emerging from mid‑20th‑century American styles like rhythm & blues, country, and gospel-inflected rock and roll, rock quickly expanded in scope—absorbing folk, blues, and psychedelic ideas—while shaping global youth culture. Core sonic markers include electric guitar (often overdriven), electric bass, drum kit emphasizing beats 2 and 4, and emotive lead vocals. Rock songs commonly use verse–chorus structures, blues-derived harmony, and memorable melodic motifs, ranging from intimate ballads to high‑energy, stadium‑sized performances.

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.
