In calligraphy, why do some people say that there is an error in the senses and "music" is sideways?

Tian Yingzhang, a doctor of calligraphy, believes that the first is the inheritance of calligraphy. As we all know, no matter what style you practice, calligraphy pays attention to inheritance. The other is that if the font is written like an artist's print, it will lose the beauty and significance of calligraphy. It is not impossible to write horizontally, but we should adjust the aesthetic feeling of the words as a whole to avoid being too rigid and lacking charm.
