This is an extremely popular martial art of Korean origin and one of the most popular practiced arts in the U.S., although sometimes advertised under the name of Karate or Korean Karate for marketing reasons as this name is more widely accepted as a martial art in America.
Although the system uses a traditional belt to denote rank, many schools do not wear a black belt, instead swapping that for a midnight blue coloured belt. This is because of the ancient Korean belief that black symbolised death and therefore and end, whereas the level of first dan instead means the beginning of real study. Masters are usually awarded their title on achievement of fourth dan.
Important characteristics which underpin the art are: humanity, righteousness, etiquette, wisdom and trust. The origins of modern Tang Soo Do lie in the kicking arts of Taekyon and Subak systems of combat.
