Yang style is considered by most to be the world’s most popular T’ai Chi style. It is not named form an individual, but is a family name (not to be confused with the Chinese concept of polarities, yin-yang), named after the family that formalized this style. There is more than one version of this form: the Long Form (also called the Big Form) has more than 100 postures and takes significantly longer to perform than many styles (usually about thirty minutes, at normal speed). Beginners usually opt for a shorter form, such as the shortened form developed by Cheng Man-Ch’ing, or the Yang 24, developed by the Chinese government. Cheng Man-Ch’ing, who was instrumental in bringing T’ai Chi to the West, condensed and softened the Yang Long Form. It is especially suited to Western enthusiasts as it strongly emphasizes softness and relaxation – making it an especially graceful style, though no less effective as a martial art. All three forms are taught at AYC.
