Step-by-step explanation:
How Sophie Taeuber-Arp Used Shape in Her Artwork
Sophie Taeuber-Arp, a renowned Swiss artist, was known for her innovative use of geometric shapes and the playfulness she brought to the abstract art movement, notably Dada. By choosing a primary shape like a circle, Taeuber-Arp explored its structural possibilities to make it appear active within the artwork. She aimed to achieve maximum impact through minimal means, often avoiding subjectivity in this process. This is evident in works such as Oval Composition with Abstract Motifs where interplay of red and yellow shapes within an oval structure is visible, and in Composition with Diagonals and Cross that features sharp angles contrasting dark and light. Her artwork displayed the ability to invoke joy and employed blocks and shapes of color in a dynamic manner that was distinct from the typically darker tone associated with Dada.
