The Yang Style solo forms are the most common form of Tai Chi practiced worldwide. The 108 (well, anywhere between 84 and 150 depending on who counts!) movement form is the oldest and the longest of the Yang Style teachings, compared to the standardized modern 24, 32, and 48 movement forms. Performed briskly it can be done in 20 minutes, it is generally taught at a 25-minute pace; and for advanced players can take over 30 minutes to complete.
Legend has it that the form was derived from Chen Style Tai Chi by a servant who observed the Chen practitioners, and then practiced in a long narrow hallway outside his living quarters. As a result, linear motions are emphasized with narrower stances than many other martial arts.
The form is generally taught with the first movement performed with a turn 90 degrees to the right. This is sufficient to learn the essence of Tai Chi, but for balanced health and physical conditioning it is strongly recommended to also learn the mirror reverse form. As an instructor, I practice and teach both forms so that students are able to observe the form not just from the rear, but from the front as we face each other. This accelerates your progress by clearly being able to see each move without having to guess.
During most people’s practice of Tai Chi, this form will be where you spend most of your time. While there is no replacement for sheer repetition and gradual refinement, practice of the Tai Chi Ball will amplify your progress by focused development of structural muscles, and reinforcing proper fundamentals of movement.
