Picasso, the reigning Cubist of the 20th century, invented, developed, and pursued many different styles after 1920, but frequently returned to his Cubist roots, as he did in this painting.  A wonderful example of Synthetic Cubism, the brilliant colors complementing the broken and resynthesized forms evoke the jagged, syncopated rhythms of modern jazz.  The flattened forms look as though they have been created by cutting and pasting paper onto the surface.  This exemplifies the ideal of flatness so prized by modern painters (in opposition to the Renaissance tradition of depth perspective).
