Calligraphy is a writing art with high artistic value, which by its nature allows the use of experimental materials. At the same time, it can be described as giving beautiful shapes to letters, which are the basic elements of writing and arranging them. Another definition of calligraphy is the formal interpretation of writing, which can vary and change depending on the artist's style. In this research article, the relationship between the Tachism movement and the art of calligraphy is emphasized, and the formal interpretation of the application of the tachism attitude in both the art of painting and the art of calligraphy is evaluated. This study explores the similarities between the Tachism technique employed in painting and calligraphy, both characterized by a lack of concern for readability. Calligraphers from various cultures and their works have been identified in calligraphy, which is distinguished by the sensitivity of the artists and their creations. The method used to evaluate artists is a qualitative research technique based on observation; the effect of the use of experimental calligraphy materials on the works, the relationship between the stylistic effect and the stain, and the use of stain based style arrangements with calligraphy instead of text arrangements with calligraphy are evaluated. By examining experimental interpretations and experimental solutions in calligraphy, both the different usage areas of calligraphy today are touched upon and the relationship of calligraphy with the Tachism style are interpreted.
