Which 1919 Georgia O'Keeffe painting is a large blue-and-black abstract work?

Georgia O'Keeffe's 1919 painting Blue and Green Music is a large abstract work organized around blue, green, black, and white forms. Its title connects visual movement with the expressive possibilities O'Keeffe associated with music.

The painting belongs to a crucial period in O'Keeffe's development. She had begun making highly simplified charcoal abstractions in 1915, works that Alfred Stieglitz exhibited in New York. These drawings were among the earliest wholly abstract artworks produced by an American artist.

O'Keeffe often explained that music suggested a model for making visual art without directly copying the visible world. This does not mean that Blue and Green Music illustrates a particular song. Rather, its sweeping shapes and color relationships create a sense of rhythm and motion.

The work is sometimes mixed up with O'Keeffe's later paintings whose titles also refer to music or sound. The year 1919 is an important clue: it places this painting in her early abstract period, before her best-known enlarged flower images dominated public recognition.
