K-pop (케이팝), short for Korean popular music is a form of popular music originating in South Korea as part of South Korean culture. It includes styles and genres from around the world, such as pop, hip hop, R&B, rock, jazz, gospel, reggae, electronic dance, folk, country, disco, and classical on top of its traditional Korean music roots.The term "K-pop" became popular in the 2000s, especially in the international context. The Korean term for domestic pop music is gayo (가요), which is still widely used within South Korea. While "K-pop" can refer to all popular music or pop music from South Korea, it is colloquially often used in a narrower sense for any Korean music and artists associated with the entertainment and idol industry in the country, regardless of the genre.

The more modern form of the genre, originally termed "rap dance", emerged with the formation of the hip hop boy band Seo Taiji and Boys, in 1992. Their experimentation with different styles and genres of music and integration of foreign musical elements helped reshape and modernize South Korea's contemporary music scene.
