Rhythm is a crucial element of xingshu, giving life and energy to each piece of calligraphy. This essay will explore the various ways calligraphers manipulate pace and movement within xingshu to express diverse moods, feelings, and visual narratives. The essay will begin by exploring the concept of "节律" (jielu) or rhythmic structure, and how different calligraphers create a unique cadence through variations in brush speed and pressure, through emphasis on particular strokes, and changes in direction. The essay will focus on how the combination of fast and slow, soft and hard, creates a sense of dynamic variation within the work. This emphasizes that rhythm is not just a metronome but a living element in the art.
