Taegeuk Yook Jang

Taegeuk Yook Jang is the sixth of eight taekwondo forms practiced by the Kukkiwon and the World Taekwondo Federation. A form, or poomsae (also romanized as pumsae or poomse), is a choreographed pattern of defense-and-attack motions. Taegeuk Yook Jang is often (but not universally) practiced by students of Kukkiwon/WTF-style taekwondo with rank of 3rd geup. Third geup students of Kukkiwon/WTF-style taekwondo practice this form in order to advance to the next rank (2nd geup).

Etymology
The word taegeuk refers to the universe from which all things and values are derived. It is also the symbol that makes up the center of the flag of South Korea and the source for its name, taegeukgi (hangul: 태극기, where gi means "flag"). The taegeuk is commonly associated with Korean Taoism philosophical values as well as Korean shamanism.

The word yook is the number 6 in the Sino-Korean numbering system. The word jang translates roughly as "chapter" or "part". Taegeuk Yook Jang translates as "Part 6 of the Taegeuk".

Symbolism
The floor pattern (or yeonmuseon) of each taegeuk poomsae is three parallel lines. On each line, a 180 degree turn is performed. The floor pattern of each taegeuk poomsae then represents three broken or solid lines, called trigrams or gwae (bagua in Chinese). Each trigram (gwae) corresponds to a natural element.
 * If the turn is performed by pivoting in-place, the line is considered to be a broken line.
 * If the turn is performed by moving the lead foot to the rear, the line is considered to be a solid line.

The first turn of Taegeuk Sa Jang is performed by pivoting in-place. The second turn is performed by moving the lead foot. The final turn is performed by pivoting in-place. This indicates that the associated trigram is a broken line, a solid line, and a broken line; this is the trigram for water ("gam"). The Kukkiwon teaches that this poomsae should be performed with movements that are fluid, as if flowing around the opponent to wear the opponent down (like water).

Techniques
This form introduces the student to a number of new techniques:
 * The movements up the stem begin and conclude with two new techniques: a twist block followed by a roundhouse kick. These create an almost "circular" method for turning from one line to the next, unlike the hard right-angle turns seen in prior forms. This is an example of the "fluid" nature of the movements in this form.
 * The final movements of the form also include two new techniques: the palm blocks, and the rearward steps into back stance and front stance. This is the only Taegeuk poomsae with rearward stepping motions. This too is an example of the "fluid" nature of the form, as the practitioner is "flowing" backward to his or her source (the beginning position of the form), like water flowing downhill.
 * The center of the form is a slow (performed to an 8-count) low opening block.

Development
During the 1920s and 1930s many of the pioneers of taekwondo studied karate or Chinese martial arts in which forms practice is seen as an essential element of the martial art. When these pioneers returned to Korea after the Japanese occupation, they incorporated forms practice into their teaching. During the 1960s there were several efforts among these pioneers to unify their styles of martial art and create a consolidated set of forms. In 1965 the Korea Taekwondo Association appointed a committee of representatives from six of the Nine Kwans to develop the forms for what is now called Kukkiwon- or WTF-style taekwondo. The committee consisted of:
 * Young Sup Lee of the Song Moo Kwan
 * Kyo Yoon Lee of the Han Moo Kwan
 * Hae Man Park of the Chung Do Kwan
 * Jong Myun Hyun of the Oh Do Kwan
 * Soon Bae Kim of the Chang Moo Kwan

In 1967, this committee introduced the Palgwae and Yudanja (Black Belt) forms (including a simpler version of Koryo). In 1971 two additional kwans joined the committee: This expanded committee went on to develop the Taegeuk forms.
 * Chong Woo Lee of Jidokwan
 * Young Ki Bae also of Jidokwan
 * Young Tae Han of Moo Duk Kwan
