What do music and calligraphy have in common?

The most important thing about calligraphy and music is its timeliness. That is, the linearity of someone's answer. ? Writing is irreversible, and a work must be written from the first stroke of the first word to the last stroke of the last word. A person who knows how to appreciate calligraphy can basically restore his writing state at that time through the calligraphy works themselves. ? For example, Yan Zhenqing's "Manuscript for Sacrificing a Nephew". Let's talk about the first six lines, that is, the period from the first year of Wei Dynasty to Lingkou, that is, the first year of Gan Yuan (AD 758), the year of the Reform Movement of China. The first day of the ninth lunar month is Gengwu Day, and the third day is Renshen. Uncle 13th (from Yan Jiming), Dr. Guanglu wears a silver seal and a blue ribbon. J.J. and Zhou Pu were added as ambassadors of the Military Affairs Secretariat of Zhou Pu. Yan Zhenqing, once awarded the title of reckless captain, was named the founding of Danyang County. Nowadays, sake and various delicacies are used to worship Yan Jiming, the nephew of Dr. Zanshan. ? In the first six lines, Yan Zhenqing wrote the first paragraph of "Sacrificing a Nephew Manuscript", which briefly explained the situation of this manuscript. We can see that the rhythm is basically coherent and unified, maintaining a relatively unified writing. This is a relatively boring process. ? From the seventh line, when writing the text of the eulogy, Yan Zhenqing's feelings began to change strongly, and his grief and indignation were manifested in the words, pen and ink began to open, and the rhythm changed obviously. Learning to appreciate calligraphy from the change of time is a necessary stage for learning to appreciate calligraphy. Calligraphy, a time art, can express one's feelings well. This is exactly the same as music. Music is not counted as a song until it is written, and so is calligraphy. It is not counted until a word is written. Different from music, the temporality of calligraphy is presented as a static carrier, which is very wonderful, and it is also the reason why the art of calligraphy is difficult for others to fully appreciate.
