What title did Georgia O'Keeffe give her 1919 abstract painting inspired by music?

Georgia O'Keeffe titled her 1919 abstract painting Blue and Green Music.

Blue and Green Music uses sweeping, interlocking forms in blue, green, yellow, and black. The title points toward O'Keeffe's interest in translating the emotional and rhythmic qualities of music into visual form. Rather than illustrating a particular song, the painting evokes movement and sound through color and shape.

O'Keeffe made several abstract works during the 1910s and early 1920s. Their simplified lines and organic forms helped establish her as a significant figure in American modernism. She later became especially famous for flowers, bones, and New Mexico landscapes, but abstraction remained essential to understanding her development.

The painting is sometimes mixed up with Arthur Dove's music-related abstractions or with O'Keeffe's later work Music, Pink and Blue. The exact title here is Blue and Green Music, and its year is 1919.
