K-pop is a cultural product that features "values, identity and meanings that go beyond their strictly commercial value." It is characterized by a mixture of modern Western sounds and African-American influences (including sounds from Hip-hop, R&B, Jazz, black pop, soul, funk, techno, disco, house, and Afrobeats) with a Korean aspect of performance (including synchronized dance moves, formation changes and the so-called "point choreography" consisting of hooking and repetitive key movements). It has been remarked that there is a "vision of modernization" inherent in Korean pop culture. For some, the transnational values of K-pop are responsible for its success. A commentator at the University of California, San Diego has said that "contemporary Korean pop culture is built on ... transnational flows ... taking place across, beyond, and outside national and institutional boundaries." Some examples of the transnational values inherent in K-pop that may appeal to those from different ethnic, national, and religious backgrounds include a dedication to high-quality output and presentation of idols, as well as their work ethic and polite social demeanor, made possible by the training period.
