What is the title of Georgia O'Keeffe's 1919 painting featuring bands of blue and green?

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

Blue and Green Music is an abstract oil painting made by O'Keeffe in 1919. Its flowing bands and curved forms suggest movement and rhythm without depicting a conventional scene or object. The title links visual abstraction to music, a comparison that frequently appeared in discussions of modernist art.

O'Keeffe created several abstract works during the 1910s and early 1920s. She often emphasized line, color, and shape instead of recognizable subjects, although she later became especially famous for flowers and Southwestern imagery.

The painting should not be confused with Music, Pink and Blue, another O'Keeffe work whose title also uses musical language. Blue and Green Music is specifically the 1919 composition named for its dominant colors and musical association.
