Which 1919 Georgia O'Keeffe painting is named for two colors and music?

Georgia O'Keeffe's 1919 painting named for two colors and music is Blue and Green Music.

The painting uses flowing bands and interlocking shapes in blue, green, and related tones. Its title suggests an attempt to translate musical qualities into visual form, a concern shared by many modernist artists who explored connections between sound, color, movement, and abstraction.

O'Keeffe made several early abstract works that did not depict identifiable objects. She later became famous for flowers, bones, buildings, and landscapes, but abstraction remained an important foundation of her artistic development.

The title is descriptive rather than the name of a musical composition. Blue and Green Music is therefore different from a song, symphony, or piece of performance music. It is a painting, created in 1919, and is associated with O'Keeffe's early modernist experiments.
