The Eight Techniques Medium Frame Solo Form developed from Master Vincent Chu's 20 years of teaching seniors. The routine he taught in his first seniors course was the 22 Techniques Tai Chi Chuan Medium Frame Solo Form abbreviated from the traditional Yang Style Tai Chi Chuan. It was too much for the nine week course so he reduced it to 15 Techniques. Due to the nature and composition of the student body, he divided the class time in half. One half focused on the 15 Techniques Solo Form and the other half on the exercises from the Tai Chi Kung. ($19.95)
