In traditional calligraphy, what is the basic purpose of the pen angle?

In traditional calligraphy, the angle at which the pen is held is crucial for enhancing the shape of the letters. The pen angle affects the thickness and thinness of the strokes, contributing significantly to the overall aesthetics of the letterforms. When the pen is positioned correctly, it allows for greater control over the varying widths of the strokes, which is essential for creating the elegant, flowing lines characteristic of calligraphy. This control helps define the unique style and personality of each letter, making it visually appealing.

While other aspects like ink flow or pressure consistency are important, they are secondary to the primary objective of achieving the desired letter shape. Therefore, understanding and mastering the pen angle is fundamental for any calligraphy practitioner aiming to create beautiful and expressive letterforms.
