4. The 37 Essential Forms
In his 1931 book, Taijiquan Method and Application (Taijiquan Shiyong Fa 太極拳使用法), Yang Chengfu
describes the thirty-seven essential forms that constitute the postural core of Yang-style Taijiquan. Once
considered to be an indispensable part of Yang-style Taijiquan training, the use of the thirty-seven forms has
largely fallen by the wayside. The Masich Internal Arts Method approach to traditional Yang-style Taijiquan
employs the martial applications that Yang presents as well as a progressive approach to thirty-seven
essential form study which explores the forms in the context of thirteen families.
