Cubism was only one step towards this new goal. Geometric shapes gave a new vision of reality. The suggestive names of paintings from Turne r to the futurists invited to overcome even this vision. Vassily Kandinsky on one hand, and the rayonists on tne other, gave the next step, taking painting to the level of abstraction of music as they filled shapes and colors with rhytm, emotion and spirituality. To these artists, a painting doesn't have to represent anything to be beautiful.
Beauty arises simply from the organization of shapes and colors.
Painting also influences sculpture and this becomes abstract too.
