To sum up, there are five aspects:
I. Scale
Size refers to the uneven change of the size of a single font in a work. It's like the change of volume in music. In cursive script, such a change is very distinct, even very abrupt. At the same time, this change also exists in seal script, official script and regular script, but there is not enough room for change like cursive script. The greater the contrast, the more distinct the rhythm. This is directly related to the style of the work. The more unrestrained the style, the greater the contrast between size. When the elegant and quiet style is displayed, the contrast of the general size is relatively small.
Second, light (virtual reality)
Paying attention to light refers to the contrast and change between virtual and real in works. Similar to the contrast and change in music between remake and pat. In calligraphy works, the main expression of emphasizing light is using ink. The concept of light and heavy refers to the emptiness and reality of ink color, and the contrast between emptiness and reality is also relative. The virtual reality is heavy, but the virtual reality is light. The shade and dryness of ink can show the severity of deficiency and excess. What needs to be clarified is that it has different understandings and concepts of coarse and fine, big and small, gathering and scattering, and long and short. Here, the main difference parameters are the virtual and real ink. Whether the thick pen is light ink and the flying white is light; A thin pen is a thick ink or solid pen, which is very heavy. Big words, gathered words, long pens, and light ink; Small print, scattered words, short pen and solid ink. There are various levels of severity, and the means used are even more diverse. When you want to express the heaviest "beat", you can use all methods to describe the "macro remake".
Third, the thickness
Thickness refers to the contrast between the width and narrowness of strokes. Similar to the treble and bass in music. In classical calligraphy works, almost all works are divided into thick and thin strokes, except the biography of the iron line and the biography of the jade seal. Just because of different styles, the degree of thickness contrast is different. If you compare a stroke to a note, when many strokes are combined, you must emphasize the change and contrast of thickness. The more obvious the contrast between thickness and thickness, the stronger the jumping feeling of its notes, and the wider its "range".
Fourth, the length
Length refers to the long and short lines of strokes. A point is the shortest line. Long lines, including straight lines and arcs, and various lines composed of various combinations of straight lines and arcs. Long lines and short lines are similar to short notes and extended notes of music. Short notes are like plucked music, while long notes are like orchestra. The short sound is urgent and sonorous, and the long sound is melodious and continuous. At this point, calligraphy and music overlap very much. The combination of long and short notes can best reflect the melody of music. The alternation of long lines and short lines can best express the rhythm of calligraphy.
