As with music, there is a distinction between court dances and folk dances. Common court dances are jeongjaemu performed at banquets, and ilmu, performed at Confucian rituals. Jeongjaemu is divided into native dances (hyangak jeongjae) and forms imported from China (dangak jeongjae). Ilmu are divided into civil dance (munmu) and military dance (mumu).
Religious dances include all the performances at shamanistic rites (gut). Secular dances include both group dances and individual performances.
Traditional choreography of court dances is reflected in many contemporary productions.

The earliest paintings found on the Korean peninsula are petroglyphs of prehistoric times. With the arrival of Buddhism from China, different techniques were introduced. These techniques quickly established themselves as the mainstream techniques, but indigenous techniques still survived.
There is a tendency towards naturalism with subjects such as realistic landscapes, flowers and birds being particularly popular. Ink is the most common material used, and it is painted on mulberry paper or silk.
In the 18th century indigenous techniques were advanced, particularly in calligraphy and seal engraving.
Arts are both influenced by tradition and realism in North Korea. For example, Han’s near-photographic "Break Time at the Ironworks" shows muscular men dripping with sweat and drinking water from tin cups at a sweltering foundry. Jeong Son’s "Peak Chonnyo of Mount Kumgang" is a classical Korean landscape of towering cliffs shrouded by mists (source : "The New York Times",. Sisters Duk Soon Fwhang and Chung Soon Fwang O'Dwyer who fled to the United States in the late 1950s avoid overtly political statements, and render seemingly benign subjects of nature—flowers, birds, fields, insects, mountains—as tempestuous and emotionally charged zones of conflict.
