TWICE

TWICE is a seminal nine-member South Korean girl group formed by JYP Entertainment in 2015. Their career is characterized by a transition from 'color pop' - a bright, high-energy blend of rock, R&B, and hip-hop - to a more mature, elegant aesthetic incorporating disco, synth-pop, and city-pop.

As one of the best-selling girl groups in history, they are credited with revitalizing the girl group market in Korea and leading the global expansion of the Hallyu wave. Their sound identity relies on the 'killing part' (a highly memorable hook), intricate vocal layering among nine members, and high-fidelity production. Critically, they are praised for their consistent output and the seamless integration of diverse genres like New Jack Swing and Latin pop into a cohesive idol-pop framework. They occupy a central position in the 'Third Generation' of K-pop, serving as a primary influence for subsequent acts like ITZY and NMIXX while maintaining a massive, dedicated global fandom known as ONCE.
