What was the title of Georgia O'Keeffe's 1919 painting featuring blue and green abstract forms?

Georgia O'Keeffe's 1919 painting of blue and green abstract forms is titled Blue and Green Music.

O'Keeffe painted Blue and Green Music in 1919, during a period when she was exploring whether visual art could communicate sensations in ways comparable to music. The work uses flowing, overlapping forms and intense colors rather than a recognizable scene.

O'Keeffe often resisted literal interpretations of her abstract paintings. Although viewers and critics have connected her forms with flowers, landscapes, or the human body, her stated interest frequently centered on line, color, rhythm, and emotional response.

The painting belongs to the early phase of her mature career, when abstraction was central to her artistic identity. It should not be confused with her later paintings of flowers, bones, or New Mexico architecture, which often have more identifiable subjects.
