Blue and Green Music is a 1919–1921 painting by the American painter Georgia O'Keeffe.

[1] The painting uses colors with an intent to capture the variance of tones that one would find in music.

[2] This piece was made while O'Keeffe was living in New York with Alfred Stieglitz.

She created many works that referenced music during this time period, saying, "I found that I could say things with color and shapes that I couldn't say any other way—things that I had no words for.

[3]" The painting is part of the Alfred Stieglitz collection, a gift by the artist to the museum in memory of her husband.
