Tangents (aka for direction & points of attack) are important in Square Form

In the Classical Tai Chi Square form, tangents refer to the points where the movement’s straight lines or angles intersect with the curved paths of the form. These tangential points mark changes in direction, where the practitioner transitions from one movement to another.

According to Master Stephen HWA, in his YouTube video on TAI CHI SQUARE & ROUND FORM, these tangents are crucial in understanding the Classical Tai Chi Square form. He emphasizes that the end of each straight line or angle is not just a physical endpoint but a point where the movement’s trajectory intersects with the curved path, creating a subtle yet significant shift in direction.

In Classical Tai Chi Square Form, tangents refer to specific movements where the practitioner’s body parts (arms, legs, or torso) intersect or touch each other, creating a dynamic, attacking-oriented pattern. These tangents serve as a means to generate power, redirect energy, and execute effective attacks.

Key Characteristics:

• Pausing at end points: Tangents in the  Square Form involve pausing at the end of each movement to ensure proper posture and preparation for the next action. This pause allows for a brief moment of “attack readiness.”

This concept is reflected in the 108-posture Classical Tai Chi Square form, where the practitioner must integrate these tangential points to maintain the form’s fluidity and harmony. The instructional videos by Classical Tai Chi offer guidance on mastering this intricate aspect of the form.

Every movement in the Square Form has a clear starting and ending point. The movement between these two points is usually in a straight line and done very crisply and resolutely. Directional changes are typically carried out at these two points. These characteristics are opposite to the Round Form, which should have a continuous movement with no apparent starting or ending point. The hand movements are mostly rounded with few straight-line movements. Therefore, directional changes do not appear at an end. Instead, it is incorporated into the movement as a smooth curvature. Also, the movement in the Round Form, instead of being crisp and resolute, should be deliberate and thoughtful. 

People are often surprised at the direct opposite requirement between the Square and Round Form. This is not unique; just think about how you learned the art of calligraphy or, for many “old timers,” how to handwrite. You first learned how to write in print form. Then, you realize the cursive form. These two writing forms are analogous to the differences between the two Taiji Forms.

By acknowledging and incorporating these tangents, practitioners can refine their technique, enhance their understanding of the form, and cultivate a deeper connection with the art of Classical Tai Chi.
