Focus on this artwork and explain the Compositions.
Kandinsky compared abstract painting to the process of musical composition, and called his major conceptual works "compositions", as opposed to his lesser "improvisations". Composition X is the last of the ten compositions he painted during his lifetime (he was 73 at the time). Unusually for Kandinsky, who attached spiritual importance to color and geometric forms, the predominant color of the painting is black, which for him evoked the closure and end of things. On the black background float various geometric shapes, whose meaning is left to the viewer's appreciation.
