What was the name of Georgia O'Keeffe's 1919 abstract painting with sweeping blue and green forms?

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

The painting belongs to O'Keeffe's early experiments with abstraction, when she explored how lines, curves, and color could communicate sensations without depicting a recognizable object. Its broad, flowing forms suggest movement and musical rhythm while remaining nonrepresentational.

O'Keeffe was influenced by the idea that visual art could express emotions comparable to those produced by music. She developed this approach in a series of charcoal drawings and watercolors in the 1910s, then continued it in oil paintings such as Blue and Green Music.

The work is sometimes confused with other paintings whose titles combine color and music, especially Music, Pink and Blue, which dates from a different part of her career. Blue and Green Music is associated with the early modernist phase that established O'Keeffe's reputation in New York.
