The simplest and most frequently used way of interpersonal communication is to speak and write. both of these methods depend on the concept of "language".
Art is an alternative way of expressing oneself and/or thoughts in a universal language. Sometimes a small work of art, such as a melody, painting, cartoon, poem, etc., offers a depth that you cannot describe in a book of hundreds of pages, and as I mentioned, this is universal. The magic part of the job is that the language itself can also be used as an art tool.
it may not even be possible to describe in words what some works of art make us think, that is, the images they describe.
