Kunmudo (군무도), alternatively spelled 'Gunmudo', is one of the Korean martial arts. It is based on dance, music and the martial art itself. The music utilises the gayageum, a Korean zither-like string instrument. In 1957, Jung-Hyo Ha founded a kunmudo-school, and started reforming the art along with his students.
Kunmudo is said to be a dance performed by ancient soldiers, and has its roots in the Silla kingdom (4th century). The Hwarang of this era were said to practise a martial art called 'Musa Chum', meaning 'sword dance' and might have been a predecessor of the modern form of Kunmudo.
The martial art itself contains both armed and unarmed techniques, and some of the weapons used includes Korean sword, spear and bow and arrow equivalents. The weapons training also include horseback riding. All techniques seem to switch between flowing elements reminiscent of T'ai chi, and explosive elements bearing some resemblance to Shaolin Kung Fu.
