Final answer:
Russian artist Wassily Kandinsky's formal spouse was Cousine Gabriele Munter. His art, including Composition VII and Improvisation 27, was influenced by his belief in the spiritual and emotional power of color.
Step-by-step explanation:
Wassily Kandinsky, a renowned Russian artist and pioneer of abstract art, was initially married to his formal spouse Cousine Gabriele Munter. They collaborated on many projects, and she supported him through his early artistic career. Kandinsky's philosophy that "Colour is the keyboard, the eyes are the hammers, the soul is the piano with many strings" influenced his colorful compositions, such as Composition VII and Improvisation 27 (Garden of Love II), which express emotional and spiritual concepts. Notably, Kandinsky faced adversities, including opposition to his art by the Soviets and the confiscation of his works labeled as 'degenerate art' by the Nazis.
