Abstract:
Words determine the speech, numbers are the basis of mathematics, musical notes make up music, all of these elements together form the specifics of the language for a particular branch. Obviously graphic arts are also based on a unique language, which has a very wide spectrum, just like the visual arts themselves.
The graphic arts are arranged alphabetically due to the elements of plastic language, which represent a specific source of communication. Just as an illiterate person would not be able to read a book, without knowing the alphabet of the specific plastic language we won't be able to understand the message that a work of art conveys.
