Jazz and progressive rock collided in an unexpected way when Richard Wright borrowed a chord from Miles Davis’ All Blues to solve a transition in Pink Floyd’s Breathe (In the Air). Searching for the smoothest way to move from G to E minor, Wright recalled a D7(#9) chord from Davis’ landmark Kind of Blue album, subtly embedding its influence into The Dark Side of the Moon. The song, rich in blues textures and atmospheric layering, showcases how Floyd’s sonic universe was shaped not just by rock and psychedelia, but also by the harmonic genius of jazz.
