Most of Paul Klee’s arts are influenced by movements in art that included Expressionism, Cubism, and Surrealism.
Klee was fundamentally a transcendentalist who believed that the material world was only one among many realities open to human awareness. His use of design, pattern, color, and miniature sign systems all speak to his efforts to employ art as a window onto that philosophical principle.
Klee challenged traditional boundaries separating writing and visual art by exploring a new expressive, and largely abstract or poetic language of pictorial symbols and signs. Arrows, letters, musical notation, ancient hieroglyphs, or a few black lines standing in for a person or object frequently appear in his work, while rarely demanding a specific reading.
