I began practicing T'ai Chi fifteen years ago. My first teacher was trained from childhood in China, then Taiwan, in the strict classical Yang Long Form. I began studying with him years later in a major U.S. city -- still Yang Long Form, still classical approach. That was a magical time, a magical experience that will be a part of me for the rest of my life.
Periodic long-distance moves have since interrupted my study several times, but these have also required me to study with teachers of quite a few T'ai Chi styles and levels of expertise. Some were more fun, some more "practical," some much more "martial" in approach, and some were sadly "lightweight."
Dr. Yang, Jwing-Ming's video is truly "the real deal." From the first frame of his performance of the entire Form, I was instantly transported back to my first Teacher's class: not only is the sequence of postures and connecting movements EXACTLY the same as where I began, but the "spirit" and "feel" of T'ai Chi is also the same as it was then. With the wide range of styles and emphases in my classes since, I'd nearly forgotten how "pure" and powerful the classical Yang form truly is!
Other reviews here have accurately described and appropriately praised the comprehensive contents and unsurpassed structure of this wonderful video that is at once a marvelous teaching tool and a true archival record of this ancient art.
I'll summarize my opinion this way:
If you EVER outgrow this DVD, please produce one of your own, so we can all study with you!
